You are studying cell cycle progression in yeast cells.If you could prevent cdc2 from associating with the mitotic cyclin,the cells would: A)arrest in G₁. B)arrest in G₂. C)arrest in S. D)arrest in prometaphase. E)arrest in metaphase.

Question

Quizplus · Accepted Answer

Cdc2 is a crucial protein kinase that, when associated with mitotic cyclin, forms the maturation-promoting factor (MPF), which is necessary for the cell to progress from G2 phase into mitosis. Preventing this association would halt the cell cycle in G2 phase, as the cell would not receive the signal to enter mitosis.
