How many chromosomes are in a cell during g2
G2 phase, Gap 2 phase, or Growth 2 phase, is the third subphase of interphase in the cell cycle directly preceding mitosis. It follows the successful completion of S phase, during which the cell’s DNA is replicated. G2 phase ends with the onset of prophase, the first phase of mitosis in which the cell’s chromatin condenses into chromosomes. WebG 2 phase comes after S phase. In S phase synthesis of DNA occurs. The amount of DNA doubles but the chromosome number or diploid content of the cell remains the same. So, if the mother cell has 32 picogram DNA in G 2, this …
