3) The basis of all PCR assays is the biochemical interaction between key components of the reaction (template, primers, nucleotide, and polymerase) during repeated cycles of denaturation, priming, j and extension (thermocycling) to rapidly and reliably copy DNA.
The enzymes that copy DNA during cell division would then grind to a halt when they encountered these genetic potholes.
Alternatively, the DNA may carry a cancer-causing gene that is activated inside the cell; activate a cancer-causing gene that has remained quiescent in the host cell; or trigger the cell's repair enzymes, which copy DNA but can make mistakes that lead to mutations.
Beese and her colleagues also plan to photograph their polymerase as it tries to copy DNA attached to known chemical carcinogens.
