Detailed explanation-1: -In this model, the two strands of DNA unwind from each other, and each acts as a template for synthesis of a new, complementary strand. This results in two DNA molecules with one original strand and one new strand.
Detailed explanation-2: -This process is known as semi-conservative replication because two copies of the original DNA molecule are produced, each copy conserving (replicating) the information from one half of the original DNA molecule. Each copy contains one original strand and one newly-synthesized strand.
Detailed explanation-3: -Each DNA molecule contains one strand of the original DNA molecule and one newly synthesized (made) strand. Therefore, DNA replication is called semiconservative. Was this answer helpful?
