Interphase consists of which phases?

Interphase consists of which phases?

• A. G1, S, and G2 phases.
• B. G0 phase only.
• C. Mitosis.
• D. Cytokinesis.

Answer: (A)

Interphase is the period between cell divisions during which the cell grows and copies its DNA in preparation for division. It includes three subphases: G1, where the cell grows and carries out normal functions; S, where DNA replication occurs; and G2, where the cell continues to grow and prepares for mitosis, ensuring all materials for division are ready. Interphase ends when mitosis begins. The other options aren’t part of interphase because G0 is a resting state outside the active cycle (though some cells can re-enter the cycle from G0), and the processes of mitosis and cytokinesis are the actual division steps that follow interphase.
