Mark the following statements about the cell cycle as true or false. If a statement is false, correct it to make a true statement.

a. During the S phase of the cell cycle, the cell stalls until conditions for division are more favorable

Hi everyone. Let's take a look at this practice problem together. Which of the following does not happen during the S phase of the cell cycle. The answer options are a checkpoint control B formation of the cell plate C DNA replication and D sister chromatid formation. So recall that S phase occurs during interphase and SS phase specifically is the phase of DNA replication and DNA synthesis during esa's DNA is doubled in order to prepare for cell division. So that means that option C is not the correct answer. DNA replication does occur during S phase. Option D is also not the correct answer. Sister chromatid formation occurs in order to prepare for cell division. Now option A checkpoint control. This also occurs during S phase DNA replication must be accurate. So if there are any errors made during replication, the cell can halt the cell cycle until the errors are corrected. So option A does occur during S phase and can be eliminated. That means that the correct answer is formation of the cell plate. This occurs specifically in plant cells and it happens during cytokinesis to divide the cytoplasm to make the two daughter cells. So the correct answer is option B formation of the cell plate. All right, everyone. I hope you found this helpful and I'll see you soon for the next practice problem.
