Question

Amplification of gene of interest by using DNA polymerase may go up to:

• A. 0.1 million times
• B. 1 million times
• C. 1 billion times
• D. 1 trillion times

Hint:

PCR can amplify DNA up to 1 billion times using thermostable DNA polymerase like Taq.

Answer 1

The Correct Option is C

Step 1: PCR (Polymerase Chain Reaction) is used to amplify DNA.
Step 2: With 30–35 cycles, the DNA can be amplified exponentially.
Step 3: Under ideal conditions, the gene of interest can be amplified up to a billion times.
