What are the products of the replication of one DNA molecule?
Select one:
A. Two strands joined into one double-stranded DNA molecule
B. Two identical double-stranded DNA molecules
C. A set of four sister chromatids
D. A pair of homologous chromosomes
E. Four identical double-stranded DNA molecules
Answer (3)
A. two identical double stranded DNA molecules.
The products of the **replication **of one DNA molecule are two identical double-stranded DNA molecules . Therefore, the correct option is B.
During **DNA replication **one DNA molecule serves as a template for the production of two identical double-stranded DNA molecules. DNA is replicated during cell division to ensure that each daughter cell receives a complete and identical set of genetic information .
Two new double-stranded **DNA molecules **identical to the original DNA molecule are produced as a result of DNA unwinding, with each strand serving as a template for the synthesis of a complementary strand. This process enables **genetic continuity **and the transfer of **genetic data **from one cell generation to the next.
Therefore, the correct option is B.

The process of DNA replication produces two identical double-stranded DNA molecules through a semiconservative mechanism where each new molecule consists of one original and one new strand. This occurs to ensure each daughter cell obtains an exact copy of genetic material during cell division. Thus, the correct choice is B.
