Question

After chromosome disjunction, cyclin B is marked for destruction by the

A. pre-replication complex.
B. CDK complex.
C. anaphase promoting complex.
D. p53 transcription factor.
E. origin recognition complex.
F. maturation promoting factor.

Answer 1

After chromosome disjunction, cyclin B is marked for destruction by the anaphase promoting complex (APC).

Step-by-step explanation:

After chromosome disjunction, cyclin B is marked for destruction by the anaphase promoting complex (APC).

The anaphase promoting complex is a protein complex that regulates the progression of the cell cycle. It targets specific proteins, like cyclin B, for degradation. Once cyclin B is degraded, it allows the cell to move from metaphase to anaphase and complete mitosis.
