WebThe process by which a DNA molecule makes its identical copies is known as DNA replication. It takes place in S-phase of interphase. There are three possible ways of DNA replication. The three possible ways are: (1) Dispersive (2) Conservative and (3) Semi-conservative. It also discuss about the evidences for semi-conservative replication. WebBasic Features of DNA Replication: All genetically relevant information of any DNA molecule is present in its sequence of bases on two strands.
