Semi-Conservative Replication
Semi-conservative replication One of the parental DNA duplex is conserved in each new duplex paired with a newly synthesized complementary strand. New strand New Parent DNA molecule Daughter DNA molecules
Semi-conservative replication One of the parental DNA duplex is conserved in each new duplex paired with a newly synthesized complementary strand
Significance of semi-conservative replication In semi-conservative replication,daughter DNA has the same information with the parental DNA.It ensures the genetic stability within the organism and the species. Semi-conservative replication is not' 一Genomic RNA absolute(influenza virus、HIV virus)。 Flu virus natomy Eaep Figure 1 virus
