Practice Questions

Q1. Gene therapy differs from gene editing in that gene therapy:

A Always uses CRISPR
B Adds a functional gene without necessarily altering the defective one Correct
C Is cheaper than gene editing
D Only works on plants

Explanation

Gene therapy introduces a functional copy of a gene to compensate for a defective one, without necessarily correcting the original mutation. Gene editing (CRISPR/Cas9) precisely modifies the DNA sequence itself. Both aim to treat genetic disorders but use different mechanisms.

Q2. How many biotech startups does India have as per IBER 2026, and how many were added in 2025?

A 8,500 total; 1,200 new
B 15,000 total; 2,500 new
C 11,855 total; 1,780 new Correct
D 20,000 total; 3,000 new

Explanation

India has 11,855 registered biotech startups with 1,780 new ones added in 2025, as per IBER 2026.

Q3. Bt toxin, used in genetically modified crops, is produced by the bacterium:

A Agrobacterium tumefaciens
B Bacillus thuringiensis Correct
C Pseudomonas fluorescens
D Escherichia coli

Explanation

Bt toxin (Cry protein) is produced by Bacillus thuringiensis, a soil bacterium. The cry gene encoding this toxin has been inserted into crops like cotton (Bt cotton) to provide insect resistance. The toxin is specific to certain insect larvae and is considered safe for humans.

Q4. Carbon nanotubes are significant in nanotechnology because they are:

A Cheap and abundant
B Extremely strong, lightweight, and excellent electrical conductors Correct
C Radioactive and useful in medicine
D Biodegradable and edible

Explanation

Carbon nanotubes (CNTs) are cylindrical molecules of rolled graphene sheets. They are 100 times stronger than steel at 1/6th the weight, conduct electricity better than copper, and have thermal conductivity exceeding diamond. Applications: composites, electronics, energy storage.

Q5. The Cartagena Protocol on Biosafety deals with:

A Deep sea mining
B Chemical weapons regulation
C Safe transfer, handling, and use of living modified organisms (LMOs) Correct
D Nuclear safety

Explanation

The Cartagena Protocol (adopted 2000, effective 2003) under the Convention on Biological Diversity addresses safe transfer and handling of LMOs, especially those crossing international borders.
