• # question_answer 123) Read the following statements about cell division and select the correct ones (i) M phase represent the phase when actual cell division occurs and I phase represents the phase between two successive M phase (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 (ii)                      B) (ii) and (iii)C) (i) and (iii)                     D) (i), (ii) and (iii)

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 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.
