Question

DNA polymerase is a protein used in many biotechnology methods that cuts DNA sequences into fragments that can then be pasted into vectors.

a. true
b. false

Answer 1

No, the claim is false; DNA polymerase does not cut DNA into fragments but synthesizes new DNA strands during PCR amplification.

Step-by-step explanation:

The statement that DNA polymerase cuts DNA sequences into fragments for biotechnology methods is false. DNA polymerase is an enzyme that synthesizes DNA molecules by adding nucleotide bases to a DNA strand. Polymerases require a primer and a DNA template to work, and they synthesize new DNA strands that are complementary to the template strands. The process of cutting DNA into fragments is actually done by a different set of enzymes called restriction enzymes. DNA polymerase is primarily used in PCR amplification, which is a technique to make many copies of a specific DNA sequence.
