NEET 2025 Biology Biotechnology Questions
Use this page to connect the official 2025 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
recombinant-DNA tools, processes and medical, agricultural and environmental applications.
Original practice preview
These are current-syllabus NeetVellum questions, shown separately from historical-paper provenance.
Example 2 · difficulty 1/5
A restriction endonuclease cuts DNA:
- A. only from the terminal nucleotide

- C. randomly at every peptide bond
- D. only after translation
Example 3 · difficulty 1/5
Which enzyme class cleaves nucleic acids but not specifically proteins?
- A. proteases
- B. lipases
- C. nucleases
- D. cellulases
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 2025 Biology Biotechnology 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 2025 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.
