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.

c. One strand of the DNA molecule is cut.

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.

blood enters the heart through two large veins, the inferior and superior vena cava, emptying oxygen-poor blood from the body into the right atrium of the heart. as the ventricle contracts, blood leaves the heart through the pulmonic valve, into the pulmonary artery and to the lungs where it is oxygenated.
