Question

you are studying cell cycle progression in yeast cells. if you could prevent cdc2 from associating with the mitotic cyclin, the cells would:
multiple choice

• arrest in prometaphase.
• arrest in metaphase.
• arrest in g₂.
• arrest in g₁.
• arrest in s.

Explanation:

cdc2 (a cyclin-dependent kinase) forms an active complex with mitotic cyclin to drive entry into mitosis from the G₂ phase. Preventing their association blocks this transition, so cells arrest in G₂.

Answer:

arrest in G₂
