The polymerase chain reaction
A) is a method for sequencing DNA.
B) is used to transcribe specific genes.

E) uses a DNA polymerase that denatures at 55°C and above.

Question

Quizplus · Accepted Answer

The polymerase chain reaction (PCR) is a method used to amplify specific DNA sequences. This is achieved through the use of specific primers designed to anneal to the target sequence, and a heat-stable DNA polymerase that can withstand the high temperatures used to denature the DNA. PCR does not involve DNA sequencing or transcription, and requires the use of specific primers to initiate DNA synthesis.
