How is the DNA of the cell affected during S-phase of the cell cycle?
Options
- ADNA amount per cell is doubled
- BDNA amount per cell is halved
- CDNA amount per cell is tripled
- DDNA amount per cell remains the same
Correct answer
A. DNA amount per cell is doubled
Step-by-step solution
The interphase of the cell cycle is divided into G 1 , S and G 2 phases. During the S phase or synthesis phase in the cell cycle, the DNA undergoes replication. Thus, the DNA is duplicated and quantity is doubled.
