Title: During what phase do centrosomes replicate in cell division? Post by: kim0394 on Oct 9, 2012 During what phase do centrosomes replicate in cell division?
I'm not sure whether its G1 or G2 Title: Re: During what phase do centrosomes replicate in cell division? Post by: trin on Oct 9, 2012 Chromosomes replicate during interphase. Specifically it occurs during S-phase which is one of three phases in interphase.
State Description Abbreviation quiescent/ senescent Gap 0 G0 A resting phase where the cell has left the cycle and has stopped dividing. Interphase Gap 1 G1 Cells increase in size in Gap 1. The G1 checkpoint control mechanism ensures that everything is ready for DNA synthesis. Synthesis S DNA replication occurs during this phase. Gap 2 G2 During the gap between DNA synthesis and mitosis, the cell will continue to grow. The G2 checkpoint control mechanism ensures that everything is ready to enter the M (mitosis) phase and divide. Cell division Mitosis M Cell growth stops at this stage and cellular energy is focused on the orderly division into two daughter cells. A checkpoint in the middle of mitosis (Metaphase Checkpoint) ensures that the cell is ready to complete cell division. |
