Question

Identify the correct statement with regard to $G_1$ phase (Gap I) of interphase.

• A. Cell is metabolically active, grows but does not replicate its DNA
• B. Nuclear division takes place
• C. DNA synthesis or replication takes place
• D. Reorganisation of all cell components takes place

Answer 1

The correct option is A Cell is metabolically active, grows but does not replicate its DNA

$G_1$-phase is metabolically active stage of cell cycle. Different type of amino acids, RNA, protein synthesis take place in $G_1$-phase but DNA replication does not take place.
(Note :- DNA replication occur in S-phase).
Nuclear division takes place during the M-phase. Reorganisation of all cell components is completed only by the end of the full cell division process.
