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

Question

Quizplus · Accepted Answer

Regulatory proteins that prevent a cell from entering the S phase in the presence of DNA damage are known as tumor suppressor proteins. These proteins help to maintain genomic stability by ensuring that only undamaged DNA is replicated. In the absence of functional tumor suppressors, damaged DNA may be replicated, leading to genomic instability and potentially allowing for the development of cancer. Neither cyclins, cyclin-dependent kinases, nor antibodies are involved in this pathway.
