APFIVE Cyclin-Dependent Kinases and Cell Cycle Regulation
A student investigating the role of cyclin-dependent kinases (CDKs) in the cell cycle treated cells with a chemical that inhibits CDK activity. They observed that the cells continued to progress through the cell cycle and concluded that CDKs are not essential for cell cycle progression. What was the mistake in the student’s conclusion?
A
The cell cycle does not involve CDKs; it is solely regulated by cyclins.
B
CDKs are only involved in the apoptosis process, not in the cell cycle progression.
C
The chemical might not have effectively inhibited CDK activity, or there are redundant pathways that can compensate for the lack of CDK activity.
D
The student’s conclusion was correct; CDKs are not essential for cell cycle progression.
