Question

Normal cellular activities, such as protein synthesis occur primarily during

• A. Interphase
• B. Anaphase
• C. Metaphase
• D. Prophase

Answer 1

The correct option is A Interphase

Interphase is the longest phase in cell cycle. Interphase comprises of first growth phase or G${}_1$ phase, synthesis or S phase and second growth phase or G${}_2$ phase.

Interphase is the phase of intense biochemical activity and prepares the cell for division. Three major processes during interphase are (a) replication of DNA and synthesis of nuclear proteins (b) duplication of centriole in animal cells (c) synthesis of energy rich compounds.
