Specific Cancer Marker Detection - The Underlying Technology

The goal of this experiment is to understand the DNA amplification process in order to detect cancerous genes when given Template DNA; otherwise known as DNA taken from the patient. DNA amplification will allow the cancerous genes to replicate. The cancerous gene will produce a positive result, while the non-cancer gene will give a negative result, because the primers are designed to amplify cancerous DNA. Therefore, the cancerous mutation cannot bind to normal DNA, ultimately meaning that amplification cannot occur.

The following “3 steps” are repeated for 30 cycles, each step taking about 30 seconds.

Step 1:Heat up the Template DNA, Primers, Taq Polymerase, and Magnesium Chloride (MgCl2) to 95 degrees Celsius

• What happens?
o The bases need to me detected, in order to do so “melting” or unzipping needs to DNA will expose those base pairs. o When the base pairs are exposed the primers will create a forward and reverse strand appropriately. The primers are short pieces (about 20 bases pairs long) of DNA that are synthesized DNA that binds to the Template DNA while directing the new strand to be made.
Step 2:The mixture is cooled down to 57 degrees Celsius

• What happens?
o The primers “anneal,” or in other words the bond.
Step 3:Heat the mixture back up to 72 degrees Celsius.

• What happens?
o The Taq Polymerase and Magnesium Chloride will detect where the template DNA and primer and uses the template DNA strand and primer to build a new copy of DNA

(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.)
