NEETBotanyCell Cycle and Cell Division
When does DNA synthesis occur during the cell cycle?
Options
- AAt the beginning of the cell cycle
- BAt the end of the cell cycle
- CThroughout the cell cycle
- DOnly at a specific stage of the cell cycle
Correct answer
D. Only at a specific stage of the cell cycle
Step-by-step solution
Cell division is a very important process in all living organisms. During the division of a cell, DNA replication and cell growth also take place. All these processes, i.e., cell division, DNA replication, and cell growth, hence, have to take place in a coordinated way to ensure correct division and formation of progeny cells containing intact genomes. Although cell growth (in terms of cytoplasmic increase) is a continuous process, DNA synthesis occurs only during one specific stage in the cell cycle . The replicat
