Question

DNA replication involves unwinding two strands of parent DNA, copying each strand to synthesize complementary strands, and releasing the parent and daughter DNA. Which of the following accurately describes this process?

a) Semi-conservative replication
b) Conservative replication
c) Dispersive replication
d) Replication fork synthesis

Answer 1

DNA replication is a semi-conservative process where each parental DNA strand acts as a template for synthesizing a new complementary strand. After replication, each DNA molecule consists of one parental and one newly synthesized strand.

Step-by-step explanation:

DNA replication is a semi-conservative process, meaning that each parental DNA strand acts as a template for synthesizing a new complementary strand. After replication, each double-stranded DNA molecule consists of one parental or "old" strand and one newly synthesized "new" strand. This process involves unwinding the two strands of parent DNA, copying each strand to synthesize complementary strands, and releasing the parent and daughter DNA.
