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?
C: Karyokinesis
D: Synthetic phase
A: Cytokinesis
B: Metaphase
Phases of Interphase: S Phase (Synthesis) -
Marks the period during which DNA synthesis or replication takes place. During this time, the amount of DNA per cell doubles, but number of chromosomes remain same.
- wherein
During this time, the amount of DNA per cell doubles, but a number of chromosomes remain same.
Cell cycle completes in two steps- Interphase and M-phase. Interphase is completed in three successive stages G1-phase (post-mitotic phase), S-phase (synthetic phase) and G2-phase (pre-mitotic or post-synthetic phase). In the given figure, D is representing the S-phase (synthetic phase) of cell cycle.

C: Karyokinesis
Incorrect
Option 2)
D: Synthetic phase
Correct
Option 3)
A: Cytokinesis
Incorrect
Option 4)
B: Metaphase
Incorrect
