Regulatory proteins that serve to prevent a cell from entering the S phase under conditions of DNA damage are also known as
A) antibodies.
B) tumour suppressors.
C) cyclin- dependent kinases.
D) cyclins.

Question

Quizplus · Accepted Answer

Tumor suppressors are regulatory proteins that help to prevent a cell from entering the S phase under conditions of DNA damage. Antibodies are not regulatory proteins involved in the cell cycle control. Cyclin-dependent kinases and cyclins are proteins involved in regulating the cell cycle, but they do not specifically prevent cells from entering the S phase under conditions of DNA damage.
