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.

How is DNA replication Semiconservatively?

According to the semiconservative model, after one round of replication, every new DNA double helix would be a hybrid that consisted of one strand of old DNA bound to one strand of newly synthesized DNA. ... Then, during the second round of replication, each double helix would be copied in its entirety.

Why is DNA semi-conservative?

DNA replication is semi-conservative because each helix that is created contains one strand from the helix from which it was copied. The replication of one helix results in two daughter helices each of which contains one of the original parental helical strands.
