Mitosis results in producing two cells w | Class 11 Biology Chapter Cell cycle and Cell Division, Cell cycle and Cell Division NCERT Solutions

Question:

Mitosis results in producing two cells which are similar to each other. What would be the consequence if each of the following irregularities
occur during mitosis?
a. Nuclear membrane fails to disintegrate
b. Duplication of DNA does not occur
c. Centromeres do not divide
d. Cytokinesis does not occur.

Answer:

If nuclear membrane fails to disintegrate then the spindle fibres will not be able to reach to the opposite poles and do not form chromosomes.
If duplication of DNA does not occur then no mitosis will occur.
If centromeres do not divide then sister chromatids would not split to opposite poles and one daughter cell would get two sister chromatids whereas the other will get none.
If cytokinesis does not occur then polyploidy appears.
