NEET 2021 Biology Cell Cycle and Cell Division Questions
Use this page to connect the official 2021 paper with current Biology practice. NeetVellum does not claim a chapter appeared in that paper until the official question and final key have been mapped.
What to master
cell-cycle control, mitosis, meiosis and chromosome behaviour.
Original practice preview
These are current-syllabus NeetVellum questions, shown separately from historical-paper provenance.
Example 2 · difficulty 2/5
During G₂ phase, a cell primarily:
- A. synthesises proteins needed for mitosis
- B. replicates all nuclear DNA for the first time
- C. pairs homologous chromosomes
- D. completes cytokinesis
Example 3 · difficulty 1/5
Cells that leave the cycle and remain metabolically active but non-dividing enter:
- A. S phase
- B. G₀ phase
- C. anaphase
- D. diakinesis
The evidence-first practice loop
- 1. Verify provenanceOfficial paper and final key before accepting a PYQ label.
- 2. Attempt closed-bookExpose the concept or execution gap before rereading.
- 3. Repair and returnClassify the miss and re-practice after a delay.

Frequently asked questions
Are these official NEET 2021 Biology Cell Cycle and Cell Division PYQs?
No. The previews are original NeetVellum practice questions. A historical item receives a PYQ label only after its official paper and authoritative final answer key are attached. Use the official archive for the source paper.
How should I use the NEET 2021 paper?
Solve the official paper under its original timing, verify against the final key, classify every miss, and then use the linked current-syllabus practice bank to repair the exposed concept.
