DNA REPLICATION

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Failure of cell division after DNA replication-
A
Mutation
B
Proofreading
C
Polyploidy
D
none of these
Explanation: 

Detailed explanation-1: -A failure in cell division after DNA replication results into chromosomal anomaly.

Detailed explanation-2: -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.

Detailed explanation-3: -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-4: -<br> Reason : A failure in cell division after DNA replication results into cheomosomal anomaly.

Detailed explanation-5: -DNA replication occurs without increasing the chromosome number; in this way, there is enough DNA in the cell for two daughter cells, maintaining the same ploidy (number of chromosomal sets) as the parent cell.
