As the cell enters M phase, the condensins are activated as a result of
A) proteolytic cleavage by checkpoint proteases.
B) dephosphorylation by cyclin dependent and Aurora B phosphatases.
C) ubiquitylation by cyclin dependent ubiquitin ligases.
D) phosphorylation by both Cdk1 and Aurora B kinase.

Question

Quizplus · Accepted Answer

The condensins are activated as a result of phosphorylation by both Cdk1 and Aurora B kinase as the cell enters M phase. This enables them to properly condense and organize the chromosomes during mitosis.
