WebApr 9, 2024 · 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. For this reason they are said to work in a 5' to 3' direction. WebChromosomes. Introduction. When a cell divides, one of its main jobs is to make sure that each of the two new cells gets a full, perfect copy of genetic material. DNA and genomes. Chromatin. Chromosomes.
