Final answer:
The correct answer to which components represent interphase is b. G1, S, and G2.
Step-by-step explanation:
The cell cycle is an orderly sequence of events in cells that leads to cell division. The interphase of the cell cycle includes three main components: G1 (First Gap), S (Synthesis of DNA), and G2 (Second Gap). In G1 phase, cells grow and synthesize proteins and prepare to replicate DNA. During the S phase, DNA replication occurs, ensuring identical genetic material for daughter cells. G2 phase involves further growth and synthesis of proteins necessary for cell division.
Cytokinesis, the division of the cytoplasm, occurs after mitosis and is not part of interphase. Therefore, the components of interphase are only G1, S, and G2. Mitosis, which includes karyokinesis (nuclear division), follows interphase and precedes cytokinesis. It is part of the M phase, not interphase.
