semiconservative replication

semiconservative replication
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 synthesized at the preceding S phase. The existence of semiconservative replication was demonstrated by the Meselson-Stahl experiment and implies the two- or multi-strandedness of DNA.
