Question

Read the following statements about cell division and select the correct ones.
(i) M phase represents the phase when actual cell division occurs and I phase represetns the phase between two successive M phases.
(ii) In the 24 hours average duration of cell cycle of a human cell, cell division proper lasts for only about an hour.
(iii) M phase constitutes more than 95% of the duration of cell cycle.

Answer 1

Answer:

Cell cycle consists of two basic phases, long nondividing I phase and a short dividing M phase . In the average duration of 24 hours in the cell cycle of dividing human cell , M phase lasts for one hour (less than 5% of total) while I phase or interphase occupies 75−95% of total generation time.

So, the correct answer is '(i) and (ii)'.
