Question
Mitosis results in producing two cells which are similar to each other. What would be the consequence if the following irregularities occur during mitosis?
Duplication of DNA does not occur

Solution
If DNA duplication does not take place, then the cell may not be able to reach the M phase. This will result in the cessation of the cell cycle.
