1.	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.A. i and iiB. ii and iiiC. i and iiiD. i,ii and iii
Answer» Correct Answer - A Cell cycle consists of two basic phases, long non-dividing I phase and a short-dividing M phase. In the average duration of 24 hours in the cell cycle of a 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.
