WebThe cell cycle has two major phases: interphase (G0, G1, S, G2) and the mitotic phase (M). The cell cycle is an ordered series of events involving cell growth and cell division that produces two new daughter cells. WebApr 9, 2024 · Chromosome and DNA Replication When the cell enters S-phase in the cell cycle (G1-S-G2-M) all the chromosomal DNA is replicated. This is done by enzymes called DNA polymerases. All DNA polymerases synthesize new strands by adding nucleotides to the 3'OH group present on the previous nucleotide.
