Detailed explanation-1: -Sister chromatids begin to separate. Failure of this stage to occur prior to mitosis would result in daughter cells without sufficient DNA.

Detailed explanation-2: -A failure of the mitotic process generates cells that carry abnormal chromosome numbers. Such cells are predisposed to become tumorigenic upon continuous cell division and thus need to be removed from the population to avoid cancer formation.

Detailed explanation-3: -Mitosis ends with telophase, or the stage at which the chromosomes reach the poles. The nuclear membrane then reforms, and the chromosomes begin to decondense into their interphase conformations. Telophase is followed by cytokinesis, or the division of the cytoplasm into two daughter cells.

Detailed explanation-4: -Nondisjunction, in which chromosomes fail to separate equally, can occur in meiosis I (first row), meiosis II (second row), and mitosis (third row). These unequal separations can produce daughter cells with unexpected chromosome numbers, called aneuploids.

Detailed explanation-5: -The cell cycle will not proceed to the next stage. Due to which the subsequent division will not happen. This will lead to cell death.
