Respuesta :
The stage of mitosis that is being described is the anaphase. It is the stage after the metaphase where the chromosomes that are replicated are splitted and the chromatids are to be moved to the poles of the cell due to the spindle's action.
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
