1. Multiple choice questions.


Q1. Which of the following is the process of directly altering an organism’s genome using biotechnology?


  • (a) Cloning
  • (b) Genetic engineering
  • (c) Breeding
  • (d) Cell culture

Answer: (b) Genetic engineering.


Q2. Bt cotton produces its own insecticide due to the presence of a gene from:


  • (a) Escherichia coli
  • (b) Bacillus thuringiensis
  • (c) Agrobacterium tumefaciens
  • (d) Rhizobium

Answer: (b) Bacillus thuringiensis.


Q3. Which of the following is NOT a biosafety concern associated with biotechnology?


  • (a) Biopiracy
  • (b) Patents
  • (c) Gene therapy
  • (d) Transgenic animals

Answer: (c) Gene therapy.


2. Very Short Answer (VSA).


Q1. What is recombinant DNA technology?


Answer: Recombinant DNA technology involves combining DNA from two different sources to create new genetic combinations for scientific or medical purposes.


Q2. Define biopiracy.


Answer: Biopiracy refers to the illegal exploitation and patenting of biological resources or traditional knowledge without proper authorization or compensation.


Q3. Name the first genetically engineered human insulin.


Answer: The first genetically engineered human insulin is Humulin.


3. Short Answer Questions.


Q1. Explain the steps involved in the production of human insulin by recombinant DNA technology.


Answer: The gene encoding human insulin is inserted into a plasmid vector and introduced into a suitable host, usually E. coli. The transformed bacteria are cultured and synthesize insulin. The insulin is then separated, purified, and mixed to form functional human insulin for therapy.


Q2. What are genetically modified (GM) crops? Give an example and its benefit.


Answer: Genetically modified crops have altered DNA to express desired traits. For example, Bt cotton contains a gene from Bacillus thuringiensis, enabling the plant to produce a protein toxic to pests, reducing the need for chemical pesticides and enhancing crop yield.


Q3. How does gene therapy work to treat genetic disorders?


Answer: Gene therapy introduces normal genes into cells to replace defective or missing ones. This helps correct genetic disorders by enabling the body to produce functional proteins, potentially curing or improving conditions like ADA deficiency or cystic fibrosis.


Q4. State two applications of transgenic animals in biotechnology research.


Answer: Transgenic animals are used to:

  • Study gene function and regulation.
  • Produce useful proteins, like antithrombin for medical therapy.


4. True or False Questions.


Q1. Transgenic animals are created by introducing foreign genes into their genome.


Answer: True.


Q2. Gene therapy can cure all genetic disorders permanently in a single treatment.


Answer: False.


Q3. Biosafety guidelines help prevent the negative impacts of biotechnology on health and environment.


Answer: True.


3. Fill in the Blanks Questions.


Q1. The bacterium used as a source of Bt gene in genetically modified crops is _____________.


Answer: Bacillus thuringiensis


Q2. The enzyme used to join DNA fragments during recombinant DNA technology is ____________.


Answer: DNA ligase


Q3. The process of protecting the legal rights on inventions involving biological materials is known as ____________.


Answer: patenting


Advantages of Biotechnology and Its Applications for NEET Biology

FAQs on Biotechnology And Its Applications Important Questions for NEET Biology - 2026

1. What are some important NEET questions asked from Biotechnology and Its Applications?

NEET often asks about recombinant DNA technology steps, applications of biotechnology in medicine and agriculture, and biosafety issues. Questions include process flowcharts, MCQs on Bt crops, and assertion-reason types about transgenic animals or gene therapy. Clinch these by revising diagrams, definitions, application examples, and typical NEET patterns.

2. Which NEET exam topics in Biotechnology focus on genetic engineering and DNA manipulation?

Genetic engineering topics centre on steps of recombinant DNA technology, enzymes like restriction endonucleases and ligases, vectors (plasmids), and mapping processes. Examineers may set MCQs, 'match the following', or diagram-based questions about these concepts, so focus your preparation on the key enzymes and gene transfer mechanisms.

3. How should I approach assertion-reason questions in this chapter?

Read both statements carefully—assertion and reason can seem similar but differ subtly. For assertion-reason questions on GMOs, gene therapy, or insulin production, always check if the reason directly explains the assertion. Practice with past NEET-style items to get familiar with typical logic patterns seen in this chapter.

4. What chapter-wise practice questions should I cover for application topics like human insulin, gene therapy, and transgenic animals?

Focus on short notes, MCQs, and 'explain process' questions covering:

  • Steps of human insulin synthesis using rDNA technology
  • Applications and steps of gene therapy
  • Benefits and significance of transgenic animals

Diagram practice often helps here as well.

5. What is a common exam-focused mistake students make regarding Bt crops and biosafety?

A frequent mistake is confusing Bt crops’ mechanism (Cry protein production) or mixing up biosafety vs. biopiracy. Clarify that Bt toxin affects insect gut, not humans, and remember biosafety includes rules to prevent risks. Revise basic definitions and real-world examples to avoid these errors.

6. Are numericals or diagram-based questions important in Biotechnology and Its Applications for NEET?

Though rare, diagram-based questions may appear – especially for recombinant DNA process flowcharts and plasmid/vector maps. Label all steps, enzymes, and regions accurately. Numericals are less common. Practice clear diagram labelling and sequence identification to tackle image-based questions if asked.

7. What revision tips would help answer NEET important questions from this chapter?

Summarise all important steps, revise diagrams (vectors, process maps), and memorise key applications of biotechnology. Use quick revision notes for differences between GMOs and transgenics, real-life examples, and key biosafety/biopiracy definitions. Practise a variety of question types (MCQ, assertion-reason, short notes) for full coverage.
