WebApr 11, 2024 · Actin disruption and cell-cycle progression from G1 to S and G2 phases only had a limited effect on G(ω) in living cells. On the other hand, G(ω) was found to be dependent on cell metabolism; ATP-depleted cells showed an increased elastic modulus G′(ω) at low frequencies, giving rise to a constant plateau such that G(ω)=G0+A(−iω)1/2 . WebVideo transcript. Now, the cell cycle is not the sort of thing that occurs in a very unchecked manner. There's actually a lot of regulation in play here. In fact, there are two key places that we have extensive regulation of the cell cycle. The first check point is right here between the G1 and the S phase.
