Foreword
"If you want truly to understand something, try to change it" (Kurt Lewin) This page is the course homepage for the "Recombinant DNA Techniques" (840:153g) lab at the University of Northern Iowa. Current version: Fall 2010! This page will be updated each summer.

You may want to watch this really good video from Drew Endy before (or after) you read on. Please also read his groundbreaking article about Foundations for Engineering Biology.

Course Overview
During this course, you will be introduced to basic techniques for cloning and recombining DNA. The principles of gene cloning, DNA manipulation and analysis will be addressed from a practical view. This lab requires designing your own experiments, self experimentation, record keeping, discussion, writing and reporting. Each session requires good preparation by the student for the laboratory tasks at hand.

Upon completion of the course, you will
 * 1) understand how gene sequences are translated into protein in different organisms
 * 2) conceptually understand how to manipulate DNA and create functionally recombined DNA fragments
 * 3) be able to practically identify, analyze, and functionally recombine DNA molecules

You will have a broad overview over the most common procedures used in a molecular biology laboratory. This includes isolating DNA from different organisms, amplifying DNA through PCR, ligating DNA fragments together, tranforming E. coli with recombined plasmids, maintaining and growing bacterial stocks harboring recombined DNA fragments, analyzing DNA fragments on agarose gels, cutting DNA fragments with restriction enzymes, identifying DNA sequences in computer databases, designing oligonucleotides for PCR amplifications, using BLAST as a tool search for specific DNA fragments in online databases, and working with biobricks. You will be able to design and carry out simple experiments, document and explain your results. You will have demonstrated that you developed skills in finding and using genomic information stored in public repositories, analyze and summarize your findings, and logically organize and present your data.   You will work in teams of three (3!) throughout the course. Each team will design a new biological part, device, or module, assemble it, prove it, and store it in the registry of biological standard parts. Your team may use all parts stored in the registries. The kits (2007-2010) are available to you in form of DNA as described in the above link. Please make yourself familiar with how to properly use the '09 DNA distribution. READ THE INSTRUCTIONS.

Your Assignment
Like in the "International Genetically Engineered Machine" (iGEM) competition, you will work in a team to develop a new biological part, module, or device. Our teams are smaller, but I expect each team to develop something new - something that does not yet exist in the repository of biological standard parts. This is a very challenging task for the few sessions we have and not necessarily something all teams will be able to accomplish this. But please do not worry about the outcomes. The outcomes will depend to a large extend on the type of project you select to work on. And since I do not want to limit your creativity, the outcomes will NOT affect your grade. However, in order to most likely succeed, very good planning is required. The better your team plans the entire project from the beginning, the better your chances are being able to complete your project. The planning is very important and it will contribute 10% to your grade. Your team has to carefully describe your project on your project homepage and give a presentation during the third week of class. Based the quality of your presentation, the understanding you show, and completeness or your experimental design, you now may (or not) start your bench work.

It is up to each team to make a decision which new part to make. However, teams should carefully study the parts list to find something that's not already there. New parts can be as simple as a new protein coding device or regulatory region, a combination of existing parts, or something else you would like to do. However, we cannot synthesize DNA because that is too costly. Therefore, you have to work with existing parts from any of the previous parts distribution (2007, 2008, or 2009) and/or use some DNA that you can easily amplify from readily available tissue by PCR (plant tissues are generally most easy to come by). In addition to the particular part, module, or device your team wants to produce, each team needs to make sure that the new part is made biobricks compatible. This means your part must eventually be modified by site-directed mutagenesis to substitute for conflicting restriction sites (e.g. those used in the biobricks standard assembly). Finally, you (as a team) have to provide evidence that your part, module, or device is functioning in the way you predicted. Figuring out how to do this can be quite tricky. Therefore, think about an easy functional assay and discuss it with your teacher. After doing all the work, each team will write a 10+ page summary report (a summary presentation is optional). This report should be done in form of a journal article. It is worth 20% of your grade and has to be submitted the week before finals. The report must be uploaded (as MS-Word or PDF) to your project homepage for consideration. No late submissions can be accepted.

1) Select a part, module, device, or system to build
Your first team task is to select a project. You may take a look at the iGEM presentations for some ideas and an overview of what undergraduate teams achieved. However, it is completely up to you what you want to do in this class. Please do not get confused by thinking you don't know enough to design a project. Just think about what kind of FUNCTION you want your part to carry out. For example, do you want to produce a certain smell or color? Do you want to build an oscillating device or something that can be activated under certain external triggers? Do you want to build a biological sensor? Or simply convert a plant gene into a biobrick? These are just a few ideas. Do whatever you like to work on. Please do not consider the assumed complexity of your project. We will brake it down to something that is achievable. At this point, JUST FOCUS ON WHAT YOU WOULD LIKE TO WORK ON. Come with some creative and challenging ideas. Everything else is irrelevant for the design step. Be curious and select something interesting. Don't be afraid to select a project that looks challenging. We will learn something from each project - regardless of how far you get with it. So please select a project that really interests you; something you really would like to do.

Once you found something interesting to work on, find a partner who wants to work together with you or join someone in their project. Browse the parts in the registry to find out what is available to use and what you can build on to achieve your plans. Then, make a list of what needs to be done. We will discuss all proposals in the third week. I will assist you in the planning as much as you need. But you have to come with ideas for discussion and ask specific questions. I will not give you suggestions on what to do, except for the above. And I will not tell you if something is possible or not. Everything is possible and we should not limit ourselves.

2) Describe your project on the team homepage
You have to describe your project on the team homepage. The description should be very concise and contain enough details to understand the project in all its details. That includes:
 * description of the product (part, module, device, or system)
 * sources for cloning it (e.g. tissue, parts used)
 * steps required to make it
 * proof of function

Developing your ideas and figuring out what is involved is a complex task that involves all team members - and the instructor. You have to sit together and play around with your ideas. Brainstorm, make plans, assign work pieces to everyone, find information, discuss what you found, revise your concepts, look up protocols and describe your approach in your proposal. Familiarize yourself (everyone) with OpenWetWare, how to edit pages, how to link to other information, and how to upload pictures. Just use the "help" function on the left or on top of each page. Do not forget to apply for an account (which is free) as soon as possible. Do it after the first class session. You need the working account very soon. So please don't delay applying. Your experimental design, the approach you take, and the results you expect must be explained in form of a research proposal and uploaded to your project website. This proposal needs approval by the instructor before any lab work can commence.   You almost certainly will identify a couple of gaps in your knowledge that have to be addressed in order to complete or even start your project. A good selection of "need to know" questions is very helpful in developing your experimental approach. Ask yourself: "What information (about the part and the experimental procedures) do I need in order to produce and verify my part/device/system?" Prepare a list of issues you need to address!   Please be aware that the first 3 weeks will be spend developing your experimental plan rather than working in the lab. If you wish, you can consider this as the combined lecture part of the course. After you started your bench work, we will have no more lectures or formal instruction. From than on, we devote every minute to practical work and get your project accomplished.  

3) IMPORTANT: Plan your work - From session to session
Once we started lab work, each project will progress on its on pace. This is natural but it has important implications. It is impossible for me to keep track of each project and plan for you. We will have anything between 3-8 different projects and I CANNOT and will not take any responsibility for your planning. You need to plan ahead for yourself. At various stages, teams will need different amount of help and this keeps me busy. You have to let me know if you need assistance. Don't wait for me to come to you. Come to me whan you need me. Otherwise, I will very likely not become aware of your needs. So please do not hesitate to talk to me whenever you find you are stuck with something. BUT please: do NEVER ask me for materials (buffers, solutions, Agar plates, enzymes, etc.) during a session where you need it. I NEED TO KNOW THE STUFF YOU PLAN USING IN THE SESSION BEFORE YOU NEED IT. Otherwise, you will not have it when you need it. Be aware that media for growing cells need to be autoclaved and supplied with appropriate antibiotics. This usually takes an entire session and YOU NEED TO MAKE YOUR PLATES YOURSELF. YOU ALSO NEED TO MAKE THE BUFFERS YOU NEED YOURSELF. If you come to me and ask me: "do you have enzyme X - I need more now" or "we forgot to make plates, do you have some?", I will not have any for you. You need to take care of things yourself and make sure that you have everything you need. This is not very hard, but you have to do it. Please plan ahead. Otherwise you loose precious lab time and THIS WILL NEGATIVELY AFFECT YOUR GRADE. And the best time to plan is after you obtained some results and before you close the day. This is the time to think ahead about what is next, look up stocks, or ask me where to find materials. If you forget that, you will be in trouble and I can't help you. Please remember that.

Attendance Policy
Attendance at ALL laboratories is mandatory. Only religious observance, a death in the family, or serious illness/injury and a doctor\\\\\\\'s note are valid excuses. One unexcused absence from the lab will result in failure of the course. Lecture and lab sessions are always combined. There will be no formal lectures but short lecturings on specific topics may be given occasionally and if needed.

Grading
Your team needs to develop a proposal in which you describe your project in as much detail as possible. The first 20% of the grade will be given for selecting a part, module, device, developing an experimental outline to produce it. 10% will be given for completing the project proposal on your project homepage and another 10% for presenting it to class (both due by the end of week 3). However, your proposal should be complete by the end of week two to allow for a review and for making improvements. A complete proposal does not mean that you have to have all answers. You probably won't. I just expect that you have your ideas down and know what you need to do to achieve what you proposed. Each team will present its proposal in a 15 minute presentation in the last session of week 3. This presentation is worth 10% of you grade.   A large and very important part of the class grade will be based on writing a detailed lab notebook. This personal lab notebook is required and will be graded based on completeness, accuracy, and content. It should contain all experimental procedures carried out during each lab session (incl. observations, calculations, remarks, etc.), as well as description and discussion of results. Based on the results obtained, it MUST also contain a brief description of the steps you plan and materials you need for the next session. The notebook has to be written at the day of the lab - during the lab! Everyone has to write her/his own notebook. It is necessary that everyone writes a good notebook and keeps it updated. The notebook will be worth 30% of your grade!!! It will be graded 3 times during the semester (after 5, 10, 15 weeks). Notebook keeping is essential for your work and grade and therefore must be done while you work - not after. You cant take the notebooks home to finish your writing after class. There will often be lag times while experiments run. Use them for writing your lab notebook or discuss progress within your team or with me. The notebooks can never leave the lab and have to be available any time for review.  Finally, I expect each team to develop their part and test it. If a team does not accomplish it, the achievements as well as problems must be explained thoroughly in the lab notebooks and the summary report. Enough evidence must be provided in the lab notebooks that sufficient efforts have been undertaken to achieve the goals mentioned in the proposal. After all, this is real science (none of the parts you attempt to build have ever been generated) and there is no guarantee that any group will succeed (though chances are high that you will). Therefore, keeping a good notebook is essential. The individual notebook will account for 30% of the grade.  I will assign another 30% of the grade based on my individual assessment of everyone's personal contribution. Here, I will consider ideas presented during class sessions, preparation for class, background knowledge about procedures, bench performance, capability to discuss experiments and results, timeliness, cleanness of workspace, organization and handling of materials, and teamwork capabilities. I will access how well you come prepared to class (do you understand the protocols? do you understand what you are doing and why?), how well you develop your bench skills (do you improve carrying out procedures accurately? do you get clear and consistent results?) and how well you plan ahead (do you always have the materials you need or do you come ask?), and how well you contribute to bringing your project forward (do you think ahead? do you look yourself for alternatives, modification, solutions? or do you always ask me or your partner?). These contributions are worth another 30% of your grade. And please believe me: you can only perform well here if you do your homework and your planning. I will never assign homework but nevertheless you will have to do it. And believe me a second time: I will be able to judge if you come prepared or not! So please spend enough time BEFORE each session to review your progress and make sure you know that is next. In addition to my assessment, your team partner(s) will also have some say for this grade. Everyone's personal contribution will be weighed by a peer assessment, which will be done the week before finals. Peer evaluations have to be turned the week BEFORE finals (or they won't count). A FINAL NOTE OF CAUTION: It is okay to have fun in the lab and there will be times where you have to wait for gels or PCRs to finish. However, use your time wisely. Don't waste it by discussing the latest movies or last weekends party. Time for experiments is scarce enough and each team will have a very tight schedule. This is not a class where you can just sit around and talk and let others do the work! If you do, it will be reflected in your grade. And I NEVER want to see cell phones (not even for texting) and other electronic devices (iPhones or MP3 players) being used in the lab. I will confiscate them the first time used. I am serious about that (please don't try me).   Final Grade Composition:   Please be aware that are no make-ups possible in this class!!! If you miss a class, it will affect your individual contribution and your peer assessment. There will be no final exams during final week. But we will have a final review meeting (mandatory) during finals. <BR> <BR> Last word of wisdom: Don't be scared. If you prepare for each session and contribute well to this class, you will have no problems. In this class you will be honored for what you put in and what you learn. The learning experience itself accounts for 50% of the grade. If you put in a lot of effort you will learn a lot and you will receive a good grade. If you don't, then you don't. It is up to you.
