Question

what is PCR? what is it used for? what are the 3 steps? temperatures used? (5)

Sammy Universe · Accepted Answer

polymerase chain reaction = amplifies DNA
1) denaturation = separate 2 strands (95)
2) annealing = primers attached to 3' end and cooled (55)
3) elongation = taq polymerase binds to primer (72)
