Want this question answered?
Actually, DNA synthesis occurs in the interphase stage, after the G1 checkpoint and before the G2 checkpoint, in the synthesis period, sometimes referred to as the 'S' phase, though it is not in fact a phase of mitosis, but rather a part of the Interphase as a whole. I hope this is more helpful than the previous answer of; "nobody knows IDIOT."
They can actually turn into harmful cell such as cancer cells
cell grows and carries out its normal functions.
G1 is part of the interphase. The cell cycle is: mitosis, G1, S (synthesis), G2 and finally mitosis again. G1, S and G2 are all part of the interphase.
In the G1 and G2 parts of interphase, the cell is not dividing.
M to G1 and G2 to M - That answer is incorrect. The correct answer is G1 to S stage and G2 to M stage. I am 100% sure. The checkpoints are after G1, during S, and after G2. The cell cycle goes G1 (gap 1 stage of interphase) to S (synthesis stage of interphase) to G2 (gap 2 stage of interphase) to M (mitosis) to C (cytokinesis).
G1/S checkpoint
G1. There are 4 phases; - G1 (growth) - S (synthesis of DNA) - G2 (further growth) - M (mitotic division) The G1 phase is the longest, as the cell needs to go through a G0 checkpoint, which makes sure there is no damage to the DNA.
g1
cell grows and carries out its normal functions.
if you are on apex it is G1 phase
if it passes the g1 check point.
