Chromosome Movement During Anaphase is a Result Of

Question

Chromosome movement during anaphase is a result of:
A) disassembly of tubulin molecules by molecular motor proteins.
B) kinetochore shortening causing chromosomes to pull apart.
C) metaphasal plate splitting resulting in chromosomal disassembly.
D) the cohesion protein attaching to the centromeres of sister chromatids.
E) cilia movement inside the cellular structure.

Accepted Answer

During anaphase, chromosome movement is primarily due to the disassembly of tubulin molecules at the kinetochore, facilitated by molecular motor proteins, which shortens the microtubules and pulls the chromatids apart.
