Original practice preview

These are current-syllabus NeetVellum questions, shown separately from historical-paper provenance.

Example 1 · difficulty 4/5

With reference to ethical issues and regulation of biotechnology, which of the following statements is CORRECT?

  • A. GEAC is an international agency functioning under WHO that regulates genetically modified organisms throughout the world
  • B. Biopiracy means the authorised commercialisation of traditional knowledge by the government of the country of origin
  • C. Patents on products derived from traditional knowledge such as turmeric and neem have never been granted, so no challenges were ever required
  • D. A US company obtained a patent on a new variety of Basmati rice derived from an Indian farmer's variety, and this patent was challenged by India

Example 2 · difficulty 1/5

In the nomenclature of the restriction endonuclease EcoRI, the letter 'R' denotes the:

  • A. genus of the bacterium from which the enzyme was isolated
  • B. species of the bacterium from which the enzyme was isolated
  • C. strain of the bacterium from which the enzyme was isolated
  • D. order in which the enzyme was isolated

Example 3 · difficulty 2/5

The single-stranded overhangs ('sticky ends') generated when DNA is cut with EcoRI are useful in recombinant DNA technology mainly because they:

  • A. pair by complementary hydrogen bonding with matching overhangs, making it easy for DNA ligase to seal the sugar-phosphate backbone
  • B. prevent self-ligation of the vector unless a foreign insert is present
  • C. allow DNA fragments to enter host cells directly without any treatment of the cells
  • D. protect the cut DNA ends from digestion by exonucleases

The evidence-first practice loop

  1. 1. Verify provenanceOfficial paper and final key before accepting a PYQ label.
  2. 2. Attempt closed-bookExpose the concept or execution gap before rereading.
  3. 3. Repair and returnClassify the miss and re-practice after a delay.

Frequently asked questions

Are these official NEET 2018 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 2018 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.
