Question

The Structure of DNADeoxyribonucleic acid, or DNA, is found in all living organisms. The structure of DNA allows it to be quickly and easily copied so that it can be passed down through generations. An incomplete model of DNA is shown in the image Which best describes the product created through the process of DNA replication?

A.
One identical DNA molecule is created from one original DNA molecule.

B.
One identical DNA molecule is created from two original DNA molecules.

C.
Two identical DNA molecules are created from one original DNA molecule.

D.
Two identical DNA molecules are created from two original DNA molecules.

Answer 1

C. Two identical DNA molecules are created from one original DNA molecule.

Explanation: During DNA replication the double helix is copied, producing two DNA molecules that are identical in sequence to the original. Each new molecule contains one original strand and one newly synthesized strand (semi-conservative replication).
