What does “Phases of the cell cycle” actually mean in Cell Cycle & Cell Division, and why does it matter for NEET?
G1 (growth), S (DNA replication), G2 (growth) make up interphase, followed by M phase (division).
I keep getting “Phases of the cell cycle” questions wrong in Cell Cycle & Cell Division. What's the trap?
thinking DNA is copied during mitosis.
What does “Mitosis” actually mean in Cell Cycle & Cell Division, and why does it matter for NEET?
division that produces two genetically identical diploid daughter cells for growth and repair.
I keep getting “Mitosis” questions wrong in Cell Cycle & Cell Division. What's the trap?
expecting variation from mitosis.
What does “Meiosis” actually mean in Cell Cycle & Cell Division, and why does it matter for NEET?
reductional division producing four genetically different haploid gametes.
I keep getting “Meiosis” questions wrong in Cell Cycle & Cell Division. What's the trap?
thinking meiosis gives identical cells like mitosis.
What does “Crossing over” actually mean in Cell Cycle & Cell Division, and why does it matter for NEET?
the exchange of segments between homologous chromosomes during meiosis, creating variation.
I keep getting “Crossing over” questions wrong in Cell Cycle & Cell Division. What's the trap?
thinking crossing over happens in mitosis.
What is the difference between mitosis and meiosis?
Mitosis gives 2 identical diploid cells (growth/repair); meiosis gives 4 varied haploid cells (gametes).
What is the difference between haploid and diploid?
Haploid (n) cells have one set of chromosomes (gametes); diploid (2n) cells have two sets (body cells).
What is the difference between chromatid and chromosome?
A chromatid is one half of a duplicated chromosome; the two sister chromatids joined at the centromere form one chromosome.
How is Cell Cycle & Cell Division tested in NEET, and what should I focus on?
Prioritise the core ideas: Phases of the cell cycle, Mitosis, Meiosis.
What are the most common mistakes students make in Cell Cycle & Cell Division?
DNA replication happens in the S phase of interphase, before mitosis — not during it.
How do I revise Cell Cycle & Cell Division quickly before the exam?
One-page summary of Phases of the cell cycle, Mitosis, Meiosis, then timed previous-year questions.
