What do you mean by semiconservative DNA replication?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. After the completion of replication, each DNA molecule would have one parental and one newly synthesised strand.
Semiconservative DNA replication is the process by which DNA is copied during cell division. In this mechanism, each newly formed DNA molecule consists of one original (parental) strand and one newly synthesized strand. This ensures that genetic information is accurately preserved across generations. During replication, the double helix unwinds, and each parental strand serves as a template for the formation of a complementary new strand. As a result, the two daughter DNA molecules each contain one strand from the original DNA, maintaining the integrity of the genetic code while allowing for the propagation of life.
