Question

Which of the following may cause a cell to go through the phases of the cell cycle and go through mitosis? (select all that apply)

a. Rising levels of p53
b. Phosphorylation of CDK/cyclin complexes
c. The large size of the cell makes it physiologically inefficient due to its decreasing
d. surface area-to-volume ratio
e. Crowding of cells
f. Phosphorylation of target proteins by activated CDK/ cyclin complexes

Answer 1

Rising levels of p53, phosphorylation of CDK/cyclin complexes, and phosphorylation of target proteins by activated CDK/cyclin complexes can cause a cell to go through the phases of the cell cycle and go through mitosis. Option a, b and f are the correct answer.

Step-by-step explanation:

The factors that may cause a cell to go through the phases of the cell cycle and go through mitosis are rising levels of p53, phosphorylation of CDK/cyclin complexes, and phosphorylation of target proteins by activated CDK/cyclin complexes.

Rising levels of p53 can lead to cell cycle arrest and activation of DNA repair or apoptosis. Phosphorylation of CDK/cyclin complexes activates these complexes, allowing the cell cycle to progress. Phosphorylation of target proteins by activated CDK/cyclin complexes drives the cell cycle forward.
