Question

Given below is a schematic break-up of the phases/stages of cell cycle. Which one of the following is the correct indication of the stage/phase in the cell cycle?

• A. C - karyokinesis
• B. D - synthesis phase
• C. A - cytokinesis
• D. B - metaphase

Answer 1

The correct option is B D - synthesis phase

In cell cycle, there are two main phases-interphase and mitotic phase.
Interphase is divided into three stages; $G_1,S$ and $G_2$. $G_1$ is first growth phase. S is synthesis phase and $G_2$ is second growth phase.
The mitotic phase is divided into two stages - karyokinesis and cytokinesis.
Karyokinesis is divided into four stages - prophase, metaphase, anaphase and telophase.
In the given figure,
A - Karyokinesis
B - Anaphase
C - Cytokinesis
D - Synthesis phase or S phase
