Which of the Following Types of Mechanisms Defines DNA Replication

Question

Which of the following types of mechanisms defines DNA replication?
A)dispersive
B)conservative
C)semiconservative
D)liberal

Accepted Answer

Semiconservative replication is the mechanism that defines how DNA replicates. In semiconservative replication, each strand of the parent DNA molecule serves as a template for the synthesis of a new complementary strand, resulting in two daughter DNA molecules that each consist of one parental and one newly synthesized strand. This mechanism was first proposed by Watson and Crick in 1953 and has since been supported by experimental evidence. The other choices (dispersive, conservative, liberal) are not mechanisms of DNA replication.
