Cdks must be complexed with what molecule to drive one cell to the next cell-cycle stage?
A) DNA
B) Phosphorylating enzymes
C) mRNA
D) Cyclin

Question

Quizplus · Accepted Answer

Cdks (cyclin-dependent kinases) need to be complexed with cyclin molecules to become active and drive the cell cycle forward. Cyclins bind to Cdks and activate them, initiating the phosphorylation of target proteins that lead to progression to the next stage of the cell cycle. Therefore, choice D is the correct answer. Choices A, B, and C are not involved in regulating Cdks and the cell cycle progression.
