B. (P) $G_{0}$ phase is also called the quiescent stage.
C. (R) Dring $G_{2}$ phase, proteins are synthesised in preparation for mitosis.

2 D - synthetic phase

3 A-cytokinesis

4 B - metaphase

Explanation:

$C$ in the diagram has one hour duration indicates that it is ' $M$ ' phase/ Apparent division phase

BIOXI10: CELL CYCLE AND CELL DIVISION

336121 Select the correct statement about $G_{1}$ phase

1 Cell is metabolically inactive

2 DNA in the cell does not replicate

3 It is not a phase of synthesis of macromolecules

4 Cell stops growing

Explanation:

During $G_{1}$ phase, cell is metabolically active, continuously grows and carries out synthesis of macromolecules, but DNA synthesis does not take place during this phase
