Checkpoints are points between phases of the cell cycle at which a cell determines whether all the requirements necessary for ea

ch phase of the cell cycle have been properly satisfied. For example, because a cell with damaged DNA can lead to cancer if it is allowed to divide, a cell with damaged DNA usually arrests the cell cycle until the damage can be repaired. At which phase(s) of the cell cycle would a cell normally check for the integrity of its DNA

Answer:

The correct answer is - at the G1/S phase and G2/M phase.

Explanation:

The G1/S transition phase or checkpoint is a phase where the cell cycle arrested if during the evaluation of the DNA found damaged or other factors including external factors. Due to this evaluation and inadequate conditions, the cell will not enter the S phase.

The G2/M phase or transition phase is a checkpoint which takes place just before the M phase that ensures that all replicated DNA is not damaged before entering mitosis phase or M phase.

Thus, the correct answer is - at the G1/S phase and G2/M phase.

This confused me.
KonstantinChe [14]
The answer is A, denature.

As each type of enzymes has its own optimum temperature, like the temperature that they work fastest at, so if the temperature goes too high above the optimum, the 3D structure of the enzyme breaks apart and deforms and they can no longer bind with substrates thus no longer works. In this scenario, we say the enzyme is denatured.

Note that only if the temperature is too high can make the enzyme denature, if the temperature is too low, instead, the enzyme would be inactive, but once the temperature goes back to normal, they work again. Unlike denatured enzymes, which does not work even if the temperature goes back to normal.
