Question

Identify the following phases 1, 2, 3, $\&$ 4. in a eukaryotic cell cycle.

• A. M G${}_1$​ S G${}_2$​
• B. G${}_2$​ M G${}_1$​ S
• C. S G${}_2$​ M G${}_1$​
• D. G${}_1$​ S G${}_2$​ M

Answer 1

The correct option is D

G${}_1$​ S G${}_2$​ M

A eukaryotic cell cycle is divided into M-phase, G1, S and G2 phases. The M phase is further divided into prophase, metaphase, anaphase and telophase. G1, S and G2 phases are together called as the Interphase.

$G_1$ phase: Growth and normal metabolic role, S phase: Synthesis and replication of DNA, $G_2$ phase: Growth and preparation for mitosis and finally, M phase: Splitting of the genetic content of the parent cell followed by cytokinesis.
