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: -Each new double strand consists of one parental strand and one new daughter strand. This is known as semiconservative 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: -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?
Detailed explanation-5: -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.
