Medical Definition of Semiconservative replication
1.
The system of replication of DNA found in all cells in which each daughter cell receives one old strand of DNA and one strand newly synthesised at the preceding S phase.
Replication in which a double-stranded DNA (dsDNA) produces two daughter dsDNA, each of which contains one of the original chains and one newly synthesised strand.
The existence of semiconservative replication was demonstrated by the Meselson Stahl experiment and implies the two or multi strandedness of DNA.
