DNA replication is semiconservative because each new double helix contains (1) old and (1) new strand. each mother strand serves as a template for a new strand.The two strands â¦ are complementary, but not identical.
Semiconservative Replication During DNA * replication, a double stranded DNA molecule separate, and each strand is used as a template for the synthesis of a new strand. This results in the formation of two identical copies of the original double stranded molecule. This is called semiconservative replication. This term captures the idea that each round of DNA replication produces hybrid molecules each of which contains one old strand and one newly synthesized strand. The following illustration shows this process over two rounds of replication:
