Question

If cyclin concentration in the cell increases high enough, what kind of response can be expected of a normal cell?

• A. The cell will enter G${}_0$.
• B. The cell will proceed past the G${}_1$ checkpoint.
• C. The cell will begin cytokinesis.
• D. The cell will become cancerous.

Answer 1

The correct option is B The cell will proceed past the G${}_1$ checkpoint.

The increase in cyclin concentrations along with other regulators will lead to the cell initiating division. The cyclins include Cyclin D, Cyciln E, Cyclin A and Cyclin B that regulates the cell cycle through various check points by forming Cyclin/cdk complexes

So, the correct answer is 'The cell will proceed past the G

11 checkpoint'
