During which phase do the sister chromatids begin to separate and start moving toward opposite poles of the cell?
- A.
Metaphase
- B.
Prophase
- C.
Telophase
- D.
Anaphase
Correct Answer
D. AnapHaseExplanation
During Anaphase, which is a phase of cell division, sister chromatids, replicated copies of each chromosome, separate and move towards opposite poles of the cell. This separation is orchestrated by spindle fibers that attach to the centromeres of the sister chromatids and pull them apart. As a result, two distinct sets of chromosomes are formed at opposite ends of the cell, ensuring that each daughter cell receives the correct number of chromosomes during cell division. Anaphase plays a crucial role in maintaining genetic stability and ensuring the accurate distribution of genetic material to the daughter cells.Rate this question:
