WHAT IS SEMI-CONSERVATIVE DNA REPLICATION

Answer 1

Semi-conservative DNA replication is the process of DNA synthesis in which each strand of the original double helix acts as a template for a new complementary strand. During replication, the double helix of DNA is separated into two strands by an enzyme called helicase. Each single strand then serves as a template for the synthesis of a new complementary strand by DNA polymerase. The end result is two identical double-stranded DNA molecules, each containing one original parental strand and one newly synthesized daughter strand. This mode of replication was first proposed by Watson and Crick in 1953, and it has been extensively studied and confirmed since then.
