During G₁,prereplication complexes:
A)are phosphorylated by B-type cyclin-CDKs.
B)are phosphorylated by DDK.
C)bind to ORC.
D)all of the above

Question

Quizplus · Accepted Answer

During G1 phase, prereplication complexes bind to the origin recognition complex (ORC), which is responsible for initiating DNA replication. Phosphorylation of the complex by B-type cyclin-CDKs and DDK occurs later in the cell cycle during S phase, after the formation of the ORC has already occurred. Therefore, option C is the best choice.
