In 'S' phase of the cell cycle:
amount of DNA doubles in each cell.
amount of DNA remains same in each cell.
chromosome number is increased.
amount of DNA is reduced to half in each cell.
As learnt in
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 number of chromosomes remain same.
During S-phase, amount of DNA gets doubled.
Option 1)
amount of DNA doubles in each cell.
This answer is correct
Option 2)
amount of DNA remains same in each cell.
This answer is incorrect
Option 3)
chromosome number is increased.
This answer is incorrect
Option 4)
amount of DNA is reduced to half in each cell.
This answer is incorrect
