Question

The interphase is divided into three main phases. These phases are:

• A. G${}_1$-phase, M-phase and G${}_2$-phase
• B. M-phase, S-phase and divisional phase
• C. Gap 1 phase, synthesis phase and gap 2 phase
• D. M-phase G${}_2$-phase and divisional phase

Answer 1

The correct option is C Gap 1 phase, synthesis phase and gap 2 phase

Interphase is a series of changes that takes place in a newly formed cell and its nucleus before it becomes capable of dividing again. It is a period of intense synthesis and growth. The interphase takes approximately 75-95% of the entire generation time. It is further divided into three periods of phases first gap or G${}_1$-phase, synthetic or S-phase and second gap or G${}_2$-phase.
