Question

PCR method is useful for

• A. Amplification of DNA for forming billions of copies of itself.
• B. Monoclonal antibody production.
• C. Both of (A) and (B).
• D. None of the above.

Answer 1

Answer: (A)

Amplification of DNA for forming billions of copies of itself.

The polymerase chain reaction (PCR) is a technology in molecular biology used to amplify a single copy and to make multiple copies of the same fragment of the DNA. The two strands are separated and each strand is considered as the template strand for the synthesis of the new strand. In this way, many cycles are performed to produce multiple copies.

Thus, the correct answer is option A.
