semi conservative replication Describes the process by which DNA is replicated in all known cells. This mechanism of replication was one of three models originally proposed for DNA replication.

Conservative replication would leave the original, template DNA strands intact and would produce a copy composed of entirely new DNA base pairs.
Dispersive replication would produce two copies of the DNA, both containing a mixture of old and new DNA base pairs.
Semi conservative replication would produce two copies that each contained one of the original strands, and one entirely new copy.
The deciphering of the structure of DNA by Watson and Crick in 1953 suggested that the semi conservative model was correct.This was soon verified by Meselson-Stahl experiment.
The enzymes responsible for this process is a replicase, more specifically it is called DNA dependent DNA polymerase(A polymerase puts togather polymers or macromolecules)
