9.6 pg
4.8 pg
2.4 pg

DNA replication
Cell growth and protein synthesis
Preparation for mitosis
Cytokinesis

Choose the correct statements regarding cell cycle
I. Interphase is called the resting phase
II. Interphase is the time during which the cell is preparing for division
III. The interphase is divided into phases, i.e.,G_1, S and G_2-phase
IV. Interphase represents the phase between the two successive M-phases
The option with correct statements is
I and II
II, III and IV
I, II and III
I, III and IV
The interphase is divided into three main phases. There phases are
-phase, M-phase and -phase
M-phase, S-phase and divisional phase
Gap 1 phase, synthesis phase and gap 2 phase
M-phase -phase and divisional phase
