NEETBotanyCell Cycle and Cell Division
What happens during the S phase?
Options
- ADNA replication and chromosome duplication
- BCell growth and normal metabolism
- CChromosome condensation
- DCentrioles move to the opposite poles
Correct answer
A. DNA replication and chromosome duplication
Step-by-step solution
he stages through which a cell passes from one division to the next is called the cell cycle. Cell cycle is divided into two phases called (i) Interphase – a period of preparation for cell division, and (ii) Mitosis (M phase) – the actual period of cell division. Interphase is further subdivided into G1, During the G ₁ phase, the cell grows and carries out normal metabolism. Most of the organelle duplication also occurs during this phase. S phase marks the phase of DNA replication and chromosome duplication.
