NEET2023BotanyCell Cycle and Cell DivisionActual
Among eukaryotes, replication of DNA takes place in:
Options
- AG 2 phase
- BM phase
- CS phase
- DG 1 phase
Correct answer
C. S phase
Step-by-step solution
Cell cycle has two main phases: Interphase (I-phase) is the longest and metabolically active phase which has three phases, gap-1 ( G 1 ), S and gap-2 ( G 2 ). Division or M-phase, where actual mitosis (or meiosis) takes place. S phase: Also called the invisible phase. The DNA replication takes place at this phase of interphase. The 2C DNA content of a cell becomes 4C at the end of S-phase. There is no change in the ploidy level.
