WebWhat is the process of chromosome replication? During every cell division, a cell must duplicate its chromosomal DNA through a process called DNA replication. The duplicated DNA is then segregated into two daughter cells that inherit the same genetic information. This process is called chromosome segregation. In which stage DNA replication ... WebOnce the chromosomes are replicated, the cell moves into the G2 phase of interphase and awaits mitosis. The S phase is called synthesis because making a copy of the chromosome requires new DNA production, or synthesis.

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.
