WebDNA replication: The cell undergoes two divisions in meiosis i.e. meiosis I and meiosis II. Meiosis I is reduction division and meiosis II is similar to mitosis but DNA replicates only once during meiosis, i.e. before meiosis I in S phase. Suggest Corrections. 0. WebDescribe mechanisms of DNA repair. When a cell divides, it is important that each daughter cell receives an identical copy of the DNA. This is accomplished by the process of DNA replication. The replication of DNA occurs during the synthesis phase, or S phase, of the cell cycle, before the cell enters mitosis or meiosis. WebDuring Mitosis, DNA is replicated during the S phase (Synthesis phase) of Interphase. … Cells spend most of their life in Interphase before Mitosis occurs (M phase).
