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?

Chromosomes will not condense

Recombination of chromosome arms will occur

Text Solution

Verified by Experts

Anaphase Promoting Complex (APC) is a protein neces.sary for separation of daughter chromosomes during anaphase. If APC is defective then the chromosomes will fail to segregate during anaphase.
