OUR COMPANY Name: Cassaundra Kinnear Name: Katherine Underwood Name: Kyle Queen Name: Mohammed Binsheliail LAB 6 WRITE-UP Computer-Aided Design TinkerCAD TinkerCAD is a straightforward and easy to use program that allows the user to create different visual projects. The user can select from premade shapes the program offers, like spheres or cubes, and warp them in different sizes. It is also possible to change the color and combined many shapes into the desired pictures. Our Design' Our design will be a software change versus a physical change to the PCR machine. The current design of the machine is solid. It is comprised of affordable materials that are durable and reliable. However, the software is extremely simple and seems to lack something. Our idea is to add an animation to show what is actually happening within the machine. It is not going to be a microscopic view of the actually reaction, but it will be a pre-made video that will show the steps of PCR as it goes through each cycle. This will allow teachers to help students learn what is actually happening within the machine. It will also help students understand how much DNA is actually being replicated per cycle. Feature 1: Disease SNP-Specific Primers Background on the disease-associated mutation It was found the species for this variation is homo sapien. This variation is found on teh chromosome 6:149721690 and the clinical significance was listed as other. This SNP is associated with the genes SUMO4 and TAB2. SUMO4, small ubiquitin-like modifier 4, is located in the cytoplasm of cells and specifically modifies IRBA. The diseases linked to it are type 1 Diabetes, Type 2 Diabetes, nephropathy, and VKH syndrome. Primer design Disease SNP-specific Forward Primer: CACCACTTAGTAAACTAATG Reverse Primer: CGTAAGAGTTAATCTTTTGA How the primers work: After separating the DNA from the double helix design into single strands, the primer binds with the DNA if and only if the primer and the existing DNA are complementary. They will continue to replicate at this point. If the template contains the non-disease allele PCR should not occur. This is due to the disease-specific primer and template not binding 1oo% to the non-disease allele because the non-disease allele had a sequence of GTG, when the disease-assocoated allele has a sequence of ATG. Feature 2: Consumables Kit The consumables kit will be held within a small b ox. This will include all the materials needed to preform a small number of PCR reactions. All items will be packaged in groups based on the item. They will then be labeled with a short description, and then they will be placed in the consumables box. This includes 1. Variety of Tubes, including the PCR tubes 2. SYBR Green I sample 3. Micro Pipette Tips 4. Primer sample 5. Micro-pipette 6. Tray to hold tubes Feature 3: Hardware - PCR Machine & Fluorimeter The new design for the software will allow for easier teaching and better understanding of why the PCR machine is being used. It gives a visual to all of the confusing words and terms being thrown around when describing the PCR process. The video will contain narration and labels for each component of the replication process. Both the PCR machine and Fluorimeter will be packaged in separate boxes for clarity and then placed in a larger box, along with the consumables kit. They will both come dismantled but this will include an easy to follow, picture instructions to help users easily mantle the PCR machine and Fluorimeter. Bonus Opportunity: What Bayesian Stats Imply About The BME100 Diagnostic Approach When looking into the PCR results, it was made clear that the machine did not do the best job at predicting illness. For the percentage of people who developed the disease and also received a positive result from the machine was not a strong percentage. Unfortunately, it was not close to one, like it ideally would be. On the other hand, the people who did not develop the illness and received a negative result was closer to 1 than the prior results. While that is a much stronger result, overall the machine does not have a strong reliability.
