Biology Question on cell cycle and cell division
Which is the longest phase of the cell cycle?
A
M-phase
B
Interphase
C
Leptotene
D
S-phase
Answer
Interphase
Explanation
Solution
Cell cycle is divided into 2 phases. (i) Interphase (a period of preparation for cell division), (ii) M phase (the actual period of cell division). The interphase cell is metabolically quite active. Interphase is the long nondividing phase further divided into G, S and G. It occupies 75 to 95% of entire cell division time.
