Questions: DNA BIOLOGY AND TECHNOLOGY · DNA AND RNA STRUCTURE INTRODUCTION LABORATORY SIMULATION E. Deoxyribose What is the product of DNA replication? A. Two daughter DNA molecules. B. One polypeptide chain of amino acids. C. One DNA molecule and one RNA molecule. D. One RNA molecule.

The answer is the first one (A): Two daughter DNA molecules.

Explanation for each option:

A. Two daughter DNA molecules.

• Correct. DNA replication results in the formation of two identical daughter DNA molecules, each containing one original strand and one newly synthesized strand. This process is known as semi-conservative replication.

B. One polypeptide chain of amino acids.

• Incorrect. Polypeptide chains are the result of translation, a process where mRNA is used as a template to synthesize proteins, not DNA replication.

C. One DNA molecule and one RNA molecule.

• Incorrect. DNA replication produces two DNA molecules, not an RNA molecule. RNA is synthesized during transcription, not replication.

D. One RNA molecule.

• Incorrect. RNA molecules are produced during transcription, not DNA replication. DNA replication results in two DNA molecules.

In summary, the product of DNA replication is two daughter DNA molecules.
