Question

Cell growth occurs during

• A. Interphase
• B. Mitotic phase
• C. Postmitotic phase
• D. Interphase and postmitotic phase

Answer 1

The correct option is D Interphase and postmitotic phase

The cell cycle has four phases as :
G${}_1$ phase - where the cell prepares for growth
S phase - where DNA synthesis takes place
G${}_2$ phase - where there is cell growth and preparation for mitosis and lastly,
M phase - where mitosis (cell division) takes place.

So, the post mitotic phase includes the G${}_1$ phase, S phase and G${}_2$ phase (called the interphase). Thus, the correct answer is option (D), 'Interphase and post-mitotic phase'.
