NEET2004BotanyCell Cycle and Cell DivisionActual
In the somatic cell cycle:
Options
- Ain G ₁ phase DNA content is double the amount of DNA present in the original cell
- BDNA replication takes place in S-phase
- Ca short inter phase is followed by a long mitotic phase.
- DG ₂ phase follows mitotic phase.
Correct answer
B. DNA replication takes place in S-phase
Step-by-step solution
Cell cycle is the series of events in which cells replicate and make two new cells. Cell cycle consists of stages- G ₁, ~S , G ₂ , and M (karyokinesis). G ₁ is the stage where the cell is preparing to divide. It then moves into the S phase where the cell copies all the DNA. S stands for synthesis phase (of DNA). After the DNA is copied and there's a complete extra set of all the genetic material, the cell moves into the G ₂ stage, where it organizes and condenses the genetic material, or starts to condense the gene
