Practice questions on Cell Cycle and Cell Division
Q1. Crossing over between homologous chromosomes takes place during which sub-stage of prophase I?
Q2. DNA replication in a eukaryotic cell takes place in:
Q3. Which stage of mitosis is marked by chromosomes lining up at the equatorial plate?
Q4. Meiosis in a diploid cell with 2n = 20 produces daughter cells with how many chromosomes each?
Quick NCERT recap
- Interphase (G1, S, G2) takes about 95% of the cell cycle; the cell grows and copies its DNA in S phase.
- Mitosis has four stages: prophase, metaphase, anaphase, telophase — chromosome number stays the same.
- Meiosis I is reductional (2n to n); meiosis II is like mitosis and keeps the number the same.
- Crossing over happens in pachytene of prophase I and is the main source of variation.
- Human cell cycle takes about 24 hours; M phase is only about 1 hour of it.
Exam tips for this chapter
- Learn the sub-stages of prophase I in order: leptotene, zygotene, pachytene, diplotene, diakinesis.
- Remember which stage the synaptonemal complex forms in and when it breaks down.
- NEET repeatedly asks about the number of chromosomes and chromatids at each stage — write it once on paper.
Common questions
How many questions come from cell cycle in NEET?
Usually one to two questions every year, and they are mostly direct NCERT lines about stages, DNA amount, or crossing over.
