B) polymerase chain reaction
C) sticky ends
D) recombinant

Question

Quizplus · Accepted Answer

Polymerase chain reaction (PCR) involves the use of complementary primers to specific regions of a DNA sequence that flanks the gene of interest. The DNA is repeatedly heated and cooled, allowing the primers to bind and the DNA to unzip. Taq polymerase then synthesizes new strands complementary to the template, resulting in exponential amplification of the target gene.
