PATHOLOGY

Detailed explanation-1: -DNA replication is said to be semi-conservative because of the process of replication, where the resulting double helix is composed of both an old strand and a new strand. Each strand of the double helix DNA would serve as a template for synthesis of a new strand.

Detailed explanation-2: -One of the most important concepts of DNA replication is that it is a semi-conservative process (Figure 7.2. 7). This means that every double helix in the new generation of an organism consists of one complete “old” strand and one complete “new” strand wrapped around each other.

Detailed explanation-3: -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.
