Question

Comment on the mechanism of PCR​

Answer 1

Answer:

POLYMERASE CHAIN REACTION (PCR).

Explanation:

Polymerase chain reaction (PCR) is a method widely used to rapidly make millions to billions of copies of a specific DNA sample, allowing scientists to take a very small sample of DNA and amplify it to a large enough amount to study in detail.

PCR is used to amplify genes associated with genetic disorders from the DNA of patients (or from fetal DNA, in the case of prenatal testing).

Answer 2

Answer:

PCR involves a process of heating and cooling called thermal cycling which is carried out by machine. There are three main stages: Denaturing – when the double-stranded template DNA is heated to separate it into two single strands
