NEET 2016 Biology Biotechnology Questions

Use this page to connect the official 2016 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 1 · difficulty 1/5

Rosie, the first transgenic cow, was genetically engineered to produce milk that is nutritionally more balanced for human babies than natural cow milk. Which human protein did her milk contain?

  • A. Human insulin
  • B. Human alpha-lactalbumin
  • C. Human growth hormone
  • D. Human serum albumin

Example 2 · difficulty 2/5

The Bt toxin produced by Bacillus thuringiensis is harmless to most organisms and remains inactive until ingested by the target insect. Why does the toxin become lethal only inside the insect's body?

  • A. The acidic pH of the insect's stomach converts the protoxin into its active form
  • B. Spores of B. thuringiensis germinate in the gut and release live bacteria that kill the insect
  • C. The alkaline pH of the insect's gut dissolves the crystals and gut proteases convert the inactive protoxin into active toxin
  • D. Sunlight activates the protoxin on the plant surface before the insect feeds

Example 3 · difficulty 2/5

In the first approved clinical gene therapy trial (1990) performed on a four-year-old girl suffering from adenosine deaminase (ADA) deficiency, lymphocytes collected from her blood were grown in culture and a functional ADA cDNA was introduced into them using:

  • A. A retroviral vector
  • B. The Ti plasmid of Agrobacterium tumefaciens
  • C. Direct microinjection of naked DNA
  • D. Calcium chloride-mediated transformation

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 2016 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 2016 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.
