Question

Identify the statement about digestion of DNA by restriction enzymes that is NOT true.

a. It generates restriction fragments.
b. It produces blunt ends. It produces sticky ends.
c. One strand of the DNA molecule is cut.
d. All of the answer choices are correct.

Answer 1

c. One strand of the DNA molecule is cut.

Step-by-step explanation:

Restriction enzymes or RE cut both strands of a DNA molecule, generating restriction fragments with sticky or blunt ends. These enzymes can cut in more than one place in the chain.

A RE creates 2 or more restriction fragments if it cuts in at least 1 place of a linear DNA nolecule or in 2 or more places of a circular DNA molecule.
