This process includes a template DNA strand, which serves as the DNA that will be replicated. Primers are also needed to artificially synthesize the DNA strand. Taq polymerase then matches base-pairs, thus replicating the DNA. Magnesium Chloride is also needed because it binds to Taq, allowing it to function. Finally, dNTP’s are the nucleotides, A, t C, and G, that are used to make the new DNA. The process includes the following: 1. Heat to 95 degrees C. This separates the complementary DNA strands 2. Cool to 57 degrees C. This allows the primers to bind to the DNA strand. 3. Heat to 72 degrees C. This allows Taq to extend the DNA copy 4. Repeat A cancer gene will produce a positive result because only when the cancer gene is present will the primer bind to the template DNA. Therefore, the DNA will be replicated exponentially, creating thousands of the same DNA sequence. If there is no cancer gene present, then the primer cannot bind to the template DNA, and the DNA will not be replicated exponentially. (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.)
