Initial Machine Testing

The Original Design
(Add image of the full OpenPCR machine here, from the Week 9 exercise. Write a paragraph description for visitors who have no idea what this is)

Experimenting With the Connections

When we unplugged (part 3) from (part 6), the machine ... (did what? fill in your answer)

When we unplugged the white wire that connects (part 6) to (part 2), the machine ... (did what? fill in your answer)

Test Run

(Write the date you first tested Open PCR and your experience(s) with the machine)


Thermal Cycler Program

DNA Sample Set-up Procedure

  1. Step 1: Student were Provided with 8 tubes of 50 μL PCR reaction mix, 8 tubes of 50 μL diluted template + primers, and disposable transfer pipettes.
  2. Step 2: Protocol planner labeled the test tube that is provided above.
  3. Step 3: 50μL of each DNA sample Mix in to test tube.
  4. Step 4: Protocol planner set up the DNA and ran the PCR reactions.

PCR Reaction Mix

  • In the PCR reaction mix there is Mix contains Taq DNA polymerase, MgCl2, dNTP's, forward primer, reverse primer.

DNA/ primer mix

  • In the DNA/ primer mix there is patient's DNA.

Research and Development

Basic DNA components:

DNA Template
DNA Polymerase
DNA Primers

First, the components are combined and heated. Once the reaction is heated to a temperature of 95 degrees Celsius, the hydrogen bonds between the DNA strands break and create two separate DNA sequences. After that, leave it to cool down to a temperature of around 55 degrees Celsius. This allow the DNA polymerase is going the bind the DNA sequence with the DNA Primer with hydrogen bonding. Once, the DNA polymerase is bound, it is going to take some of the free nucleotides from the surrounding area and complete the DNA strand. The result is a two separate DNA sequences, with two DNA strand identical to the first one. Repeatedly doing the steps and the result amount of DNA stands.

Specific Cancer Marker Detection - The Underlying Technology

(Add a write-up of the information discussed in Week 3's class)

(BONUS points: Use a program like Powerpoint, Word, Illustrator, Microsoft Paint, etc. to illustrate how primers bind to the cancer DNA template, and how Taq polymerases amplify the DNA. Screen-captures from the OpenPCR tutorial might be useful. Be sure to credit the source if you borrow images.)
