Acell is arrested during mitosis. at this stage, distinct chromatids are visible at opposite poles of the cell. which stage of mitosis does this describe?

During anaphase Chromatids move towards opposite poles where they can be seen clearly.

Further explanation

Mitosis

Such type of cell division during two similar daughter cells are produced having same chromosomes as they were present in parent cells. Mitosis maintain number of chromosomes in offspring. Replication of DNA and protein formation happens as a planning for cell division during interphase. Mitosis incorporates Cytokinesis and Karyokinesis.

Karyokinesis

It is defined as nucleus division which comprises four stages

1.Prophase (It is first stage when chromatin coils tightly)

2. Metaphase (Such phase where chromosome aligns in center)  

3.Anaphase (Anaphase is such phase where; sister chromatids are isolated at the centromere and are pulled towards inverse poles. During telophase, chromosomes land at inverse shafts and loosen up into thin strands of DNA, while spindle fiber lost and nuclear membrane again appears).

4.Telophase (Last stage of mitosis)

Importance of mitosis

Number of chromosomes remains same in both generations

Characters of parents can be conserved in daughter cells  

Asexual reproduction in both animals and plants occurs through mitosis

Drawbacks

More chances of diseases  

No crossing over
