Question

What substance builds up during interphase to later bind with CdK (cyclin dependent kinase)?

Answer 1

Cyclin builds up during interphase and later binds with CdK.

Step-by-step explanation:

During interphase, the substance that builds up and later binds with CdK (cyclin dependent kinase) is cyclin.

Cyclins regulate the cell cycle by binding to Cdks and forming Cdk/cyclin complexes. These complexes need to be phosphorylated in specific locations to become fully active. The proteins phosphorylated by Cdks are involved in advancing the cell to the next phase of the cell cycle.
