WebS phase (Synthesis Phase) is the phase of the cell cycle in which DNA is replicated, occurring between G 1 phase and G 2 phase. Since accurate duplication of the genome … 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.
WebA replicated chromosome contains two identical double strand -DNA- molecules, the chromatids, that are joined at their centromere. Two single sets of pairs (daughter) chromosomes are formed by separation of the pair of chromatids during cell division (from anaphase on in mitosis and anaphase II in meiosis)
