Assertion (A) Cell normally proceed to mitosis without
interruption, once it enters the -phase.
Reason (R) Replicated chromosomes (DNA) are distributed
to daughter nuclei by a complex series of events under
genetic control
interruption, once it enters the -phase.
Reason (R) Replicated chromosomes (DNA) are distributed
to daughter nuclei by a complex series of events under
genetic control
View answer and explanation
Correct option: D
If A is false, but R is true
Option D (If A is false, but R is true) is correct because cells do not always proceed to mitosis without interruption after G2 phase, and the distribution of replicated chromosomes is indeed under genetic control.
