DNA replication occurs prior to meiosis during … WebDuring Interphase there are 3 major steps, G1, S, and the G2 phase. In the G1 phase the cell begins creating all of the proteins required to build chromosomes and DNA.
WebThe cell cycle has two major phases: interphase and the mitotic phase (Figure 1). During interphase, the cell grows and DNA is replicated. During the mitotic phase, the replicated DNA and cytoplasmic contents are … WebIn the S phase, DNA replication results in the formation of identical pairs of DNA molecules, sister chromatids, that are firmly attached to the centromeric region. The centrosome is duplicated during the S phase. The two centrosomes will give rise to the mitotic spindle, the apparatus that orchestrates the movement of chromosomes during mitosis.
