When does DNA synthesis occur during the cell cycle?

When does DNA synthesis occur during the cell cycle?

Options

  1. AAt the beginning of the cell cycle
  2. BAt the end of the cell cycle
  3. CThroughout the cell cycle
  4. 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 replicated chromosomes (DNA) are then distributed to daughter nuclei by a complex series of events during cell division. These events are themselves under genetic control.
