NEETBotanyCell Cycle and Cell Division
Read the following statements describing key cellular events during the cell cycle: (I) DNA replication begins in the nucleus. (II) Condensation of chromosomal material begins. (III) The cell is metabolically active and continuously grows but does not replicate its DNA. (IV) Proteins are synthesised in preparation for mitosis while cell growth continues. Starting immediately after cell division, what is the correct c
Options
- AIII IV I II
- BIII I IV II
- CI III IV II
- DIII I II IV
Correct answer
B. III I IV II
Step-by-step solution
According to NCERT, the interphase is divided into three phases: G ₁ , S, and G ₂ , followed by the M phase. Statement (III) describes the G ₁ phase (Gap 1), which occurs immediately after cell division. The cell is metabolically active and grows but does not replicate its DNA. Statement (I) describes the S phase (Synthesis), where DNA replication begins. Statement (IV) describes the G ₂ phase (Gap 2), where proteins are synthesised in preparation for mitosis. Statement (II) describes prophase, which is the initiat
