Semi conservative replication is a normal process of dna synthesis, in which the two original strands of the molecule separate, and each acts as a template on which a. 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.

Matthew meselson recalls the events that led him to meet frank stahl and to perform the now famous experiment showing that dna undergoes semi-conservative replication. Dna replication is known as semiconservative replication because half of the original dna strand is conserved throughout the replication process a new strand of dna.
