What is dna replication is said to be semiconservative because?

DNA replication is said to be semiconservative because each newly synthesized DNA molecule consists of one original (parental) strand and one newly synthesized (daughter) strand. This model was first proposed by James Watson and Francis Crick in 1953.

During DNA replication, the double-stranded DNA molecule unwinds and each strand serves as a template for the synthesis of a new complementary strand. This process results in two daughter DNA molecules, each containing one parental strand and one newly synthesized strand.

The semiconservative nature of DNA replication ensures that each new DNA molecule retains the genetic information from the original DNA molecule. This is crucial for maintaining the genetic integrity of an organism and ensuring accurate transfer of genetic information to daughter cells during cell division.
