The function of the primers include attaching to sites on the DNA strands that are at either end of the segment that needs to be copied. The taq polymerase reads the DNA code and then attaches matching nucleoties to create DNA copies. | The function of the primers include attaching to sites on the DNA strands that are at either end of the segment that needs to be copied.

During the denature step at 95 degrees C for 30 seconds, the DNA double helix seperates creating two single-stranded DNA molecules. Next, during the anneal stage at 57 degrees C for 30 seconds, a single stranded DNA molecule naturally attempts to pair up. Furthermore, at the extend stage at 72 degrees C for 30 seconds the DNA polymerase is activated and adds complementary nucleotides onto the strand. Lastly. during the final stage at 72 degrees C for 3 minutes there are fragments left that only contain the target sequence of DNA. | During the denature step at 95 degrees C for 30 seconds, the DNA double helix seperates creating two single-stranded DNA molecules.

ProtocolsThermal Cycler Program
PCR reaction, 8 tubes, 50 μL each: Mix contains Taq DNA polymerase, MgCl2, and dNTP's.
DNA/ primer mix, 8 tubes, 50 μL each: Each mix contains a different template DNA. All tubes have the same forward primer and reverse primer.
Research and DevelopmentPCR - The Underlying Technology Functions Steps of Thermal Cycling (Add a write-up, essay-style, organized into paragrpahs with descriptive headers, based on the Q&A's from Section three of your worksheet) (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 PCR video/ tutorial might be useful. Be sure to credit the sources if you borrow images.)
