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.
