MCQ
Anaphase promoting complex (APC) is a protein degradation machinery necessary for proper mitosis of animal cells. If APC is defective in a human cell, which of the following is expected to occur?
  • A
    Chromosomes will not segregate
  • B
    Chromosomes will be fragmented
  • C
    Chromosomes will not condense
  • D
    Recombination of chromosome arms will occur
✓

Answer

A. Chromosomes will not segregate
Explanation:
Anaphase promoting complex helps in the transition of the chromosome from metaphase to anaphase. The anaphase-promoting complex attaches to the chromosomes aligned at the equator during metaphase and allows the segregation of the chromatids.
