Question

“DNA replication is said to be semiconservative" Why? Describe the experimental proof of
Messelson and Stahl to show DNA replication is conservative. ​

Answer 1

Answer:

1. DNA replication is said to be semi-conservative because of this process of replication, where the resulting double helix is composed of both an old strand and a new strand. ... Semiconservative replication would produce two copies that each contained one of the original strands and one new strand.
2. The experiment done by Meselson and Stahl demonstrated that DNA replicated semi-conservatively, meaning that each strand in a DNA molecule serves as a template for synthesis of a new, complementary strand. ... Some of your cells are replicating their DNA semi-conservatively right now!
