Question

In PCR, a)the gene sequence is determined. b)multiple copies of the DNA sample are made. d) DNA is destroyed so it has no value.

Answer 1

Answer:

b) Multiple copies of the DNA sample are made

Explanation:

Polymerase chain reaction is a method widely used in molecular biology allowing scientists to take a very small sample of DNA and amplify it to a large enough amount to study in detail.

The DNA polymerase enzyme used is Taq polymerase stable at high temperature.

Steps in PCR in correct order is Denaturation, Annealing and Extension.
