Detailed explanation-1: -Consequently, when DNA is replicated by the combined action of helicase and DNA polymerase: Each new strand formed will be identical to the original strand separated from the template. The two semi-conservative molecules formed will have an identical base sequence to the original molecule.
Detailed explanation-2: -Semiconservative replication is so named because one of the strands of DNA in each of the two copies of DNA is ancient and conserved while the other is newly produced at the moment of replication.
Detailed explanation-3: -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.
Detailed explanation-4: -The feature of DNA replication that makes it semiconservative is that each daughter molecule is made of one new strand and one old strand.
Detailed explanation-5: -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.
