Question

Amplification of gene of interest by using DNA polymerase may go upto ______.

Options

• 0.1 million times

• 1 million times

• 1 billion times

• 1 trillion times

Answer 1

Amplification of gene of interest by using DNA polymerase may go upto 1 billion times.

Explanation:

The target DNA sequence is amplified exponentially in the Polymerase Chain Reaction (PCR). The quantity of DNA molecules doubles with each PCR cycle. The amplification can reach up to 1 billion times (10°) the original DNA template after 30 to 40 cycles.
