The polymerase chain reaction requires endonuclease to cut samples of DNA.

Question

Quizplus · Accepted Answer

The polymerase chain reaction (PCR) does not require endonuclease to cut samples of DNA. PCR is a technique used to amplify a specific segment of DNA, and it involves repeated cycles of denaturation, annealing, and extension. Enzymes used in PCR include Taq polymerase, which adds nucleotides to the DNA strand, and primers, which provide a starting point for the polymerase to add nucleotides. Endonucleases are not necessary for PCR.
