Expert Solution

Semiconservative replication of DNA

According to the semiconservative model of DNA replication proposed by Meselson and Stahl, each strand of the double-stranded DNA serves as a template for the synthesis of a new strand. This results in the formation of two new DNA molecules, each with an old strand and a new strand. DNA replication is carried by a DNA polymerase enzyme that catalyses the polymerization in a 5' to 3' direction.
