NEET · BiologyEasy
Which structure is responsible for pulling sister chromatids apart during anaphase?
- A.Nuclear membrane
- B.Spindle fibers
- C.Cell wall
- D.Nucleolus
Show correct answer & step-by-step solution
Correct answer: B — Spindle fibers
Solution
- During anaphase, the centromeres split.
- The spindle apparatus is composed of microtubules called spindle fibers.
- These fibers shorten to pull the sister chromatids toward opposite poles of the cell.
- Hence the answer is (B).
