Question

Mitosis results in production two cell which are similar. What would be the consequence if following irregularities takes place?
a) Duplication of DNA does not occur
b) Cytokinesis does not occur​

Answer 1

Duplication of DNA does not occur: There will be no mitosis.

Cytokinesis does not occur: In some organisms karyokinesis is not followed by cytokinesis as a result of which multinucleate condition arises leading to the formation of syncytium (e.g., liquid endosperm in coconut).

Answer 2

Answer:

DNA duplication does not occur than cell might not be able to supose S-phase of cell-cycle as no chromosome formation will take place, and will not be able to enter M-(mitotic phase) or if in case it enters mitosis the cycle will cease.
