'''Specific Cancer Marker Detection - The Underlying Technology'''<br> | '''Specific Cancer Marker Detection - The Underlying Technology'''<br> | ||
A Polymerase chain reaction is a machine that amplifies a single or a few strands of DNA to generate millions of copies of that DNA sequence. Using this technology scientist can determine whether a patient has a positive or negative result towards cancer. A method of getting this data is called the PCR detection method, a method that relies on thermal cycling, switching back and forth to melt DNA and then connect primers. This is a method that can be used to detect whether a patient has positive result for cancer, because a sample of DNA can be taken and whether that connects to the primers and creates a chain reaction, scientist can determine whether this DNA is positive or negative towards cancer. An example of proving this method can be seen using the r17879961 SNP, a cancer-associated sequence, using the PCR detection method we can prove that r17879961 SNP is actually associated with cancer. Because it carries with the Polymerase chain reaction, and to further prove the patient has a positive result for cancer, we use fluorescent dye and if the DNA glows in the solution, then the results are positive for cancer. | A Polymerase chain reaction is a machine that amplifies a single or a few strands of DNA to generate millions of copies of that DNA sequence.

(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.) | (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.
