The long, multi-statement questions that dominated NEET 2025 & 2026 — each covers 5-6 concepts at once, so they double as fast full-chapter revision.
- Q1. Which of the above statements regarding Bt toxin and its pest control strategy are NOT correct? S1: Bt toxin is produced by Bacillus thuringiensis as an inactive protoxin and is activated in the insect gut by alkaline pH. S2: The primary success of Bt toxin in pest control lies in its broad-spectrum activity against all insect orders. S3: CryIAb gene is primarily effective against cotton bollworms, while CryIAc controls corn borer. S4: The activated Bt toxin binds to the surface of midgut epithelial cells, leading to pore formation and subsequent cell lysis. S5: Bt protein crystals are formed during a specific bacterial growth phase and contain the toxic insecticidal protein.
- Q2. Which of the above statements about somaclones, micropropagation, and somatic hybridisation are correct? S1: Somaclones are genetically identical plants produced through micropropagation. S2: Micropropagation is a technique that can produce thousands of plants from a single parent in a short duration. S3: Somatic hybridisation involves the direct fusion of whole plant cells from two different species. S4: The recovery of virus-free plants from diseased ones is an important application of micropropagation using meristem culture. S5: Pomato, a hybrid of potato and tomato, is an example of a successful commercial crop developed through somatic hybridisation.
- Q3. Which of the following statements accurately describes the distinctions between pro-insulin and mature human insulin? S1. Mature insulin is a pro-hormone, whereas pro-insulin is the active form. S2. Pro-insulin contains an extra polypeptide stretch called the C-peptide, which is absent in mature insulin. S3. The A and B chains in both pro-insulin and mature insulin are linked together by disulfide bridges. S4. Enzymatic removal of the C-peptide is essential for pro-insulin to become a fully functional hormone. S5. Recombinant human insulin directly synthesizes the pro-hormone in E. coli, which then matures inside the bacterial cell.
- Q4. Which of the following statements about the production of therapeutic proteins and gene manipulation is NOT correct? S1: Transgenic animals are capable of producing human therapeutic proteins such as α-1-antitrypsin for treating specific human diseases. S2: The reason transgenic animals can produce human proteins is that human DNA sequences are inserted and expressed in their somatic cells only. S3: Rosie, the transgenic cow, was engineered to produce human alpha-lactalbumin in her milk, making it nutritionally superior for human babies. S4: Therapeutic proteins like human insulin are solely produced in transgenic animals, as bacterial systems cannot properly fold complex human proteins. S5: Genetic modification for biological products in animals typically involves introducing the specific gene portion coding for the desired protein into the animal's genome.

The patient requires periodic infusion since lymphocytes are not immortal. 3. Lymphocytes are isolated from the blood of the patient. 4. The introduced gene enables lymphocytes to produce ADA enzyme. 5. A functional ADA cDNA is introduced into lymphocytes using a retroviral vector.

Which part of the tobacco plant is infected by Meloidogyne incognita?
- A. Flower
- B. Leaf
- C. Stem
- D. Root
Explanation: Answer: (4) Root Solution: The nematode Meloidogyne incognita parasitises tobacco plants by infecting their roots, causing a large reduction in yield. Resistance is engineered using RNA interference (RNAi), which silences specific nematode mRNA via dsRNA, protecting the transgenic plant. NCERT Reference: Ch 10, p.180, line 10 — "incognitia infects the roots of tobacco plants and causes a great reduction"
Which of the following statements is not correct?
- A. The functional insulin has A and B chains linked together by hydrogen bonds
- B. Genetically engineered insulin is produced in E-Coli
- C. In man insulin is synthesised as a proinsulin
- D. The proinsulin has a extra peptide called C-peptide
Explanation: Answer: (A) The functional insulin has A and B chains linked together by hydrogen bonds Solution: Insulin's A and B chains are linked by disulphide bridges, not hydrogen bonds — so statement (A) is the incorrect (not correct) one. The other statements are true: Eli Lilly produced genetically engineered insulin chains in E. coli; in humans insulin is first made as a pro-hormone (proinsulin); proinsulin carries an extra stretch called the C peptide that is removed on maturation. NCERT Reference: Ch 10, p.181, line 026 — "and chain B, that are linked together by disulphide bridges"
The two polypeptides of human insulin are linked together by:
- A. Hydrogen bonds
- B. Phosphodiester bond
- C. Covalent bond
- D. Disulphide bridges
Explanation: Answer: (4) Disulphide bridges Solution: Human insulin consists of two short polypeptide chains, chain A and chain B. NCERT states these chains are held together by disulphide bridges (disulfide bonds), not hydrogen, phosphodiester, or generic covalent bonds. During recombinant production, chains A and B are made separately in E. coli and combined by creating these disulphide bonds. NCERT Reference: Ch 10, p.181, line 26 — "Insulin consists of two short polypeptide chains: chain A"
Which kind of therapy was given in 1990 to a four-year-old girl with adenosine deaminase (ADA) deficiency? (NEET 2016 (Phase 2))
- A. Gene therapy
- B. Chemotherapy
- C. Immunotherapy
- D. Radiation therapy
Explanation: Answer: (A) Gene therapy Solution: The first clinical gene therapy was administered in 1990 to a 4-year-old girl with adenosine deaminase (ADA) deficiency. ADA is crucial for immune function; gene therapy delivers a functional ADA cDNA (via a retroviral vector) into the patient's lymphocytes to compensate for the deleted gene. NCERT Reference: Ch 10, p.182, line 25 — "The first clinical gene therapy was given in 1990 to a 4-year old girl"
