Question 1 of 16
Plants whose genes are altered by genetic engineering are called:
GM (transgenic) crops
Fossils
Vectors
Antibodies
Explanation: Such plants are genetically modified (transgenic) crops.
Question 2 of 16
Bt cotton is resistant to insect pests due to a gene from:
Bacillus thuringiensis
Yeast
Rhizobium
A virus
Explanation: The Bt gene makes a protein toxic to certain insects.
Question 3 of 16
The Bt protein in Bt cotton is toxic to:
Certain insect pests
Humans
All animals
The plant itself
Explanation: Bt protein targets specific insect pests, sparing humans.
Question 4 of 16
Golden Rice is engineered to be rich in:
Vitamin A
Salt
Sugar
Fat
Explanation: Golden Rice contains extra vitamin A (beta-carotene).
Question 5 of 16
Growing whole plants from small pieces of tissue in the lab is:
Tissue culture
Fermentation
Vaccination
Digestion
Explanation: Tissue culture grows plants from tissue (micropropagation).
Question 6 of 16
Human insulin made by bacteria is called:
Humulin
Penicillin
Interferon
Bt protein
Explanation: Genetically engineered human insulin is humulin.
Question 7 of 16
Animal insulin was sometimes a problem because it could cause:
Allergies
More energy
Better vision
No effect
Explanation: Animal insulin could cause allergic reactions in some patients.
Question 8 of 16
A vaccine made by genetic engineering containing only part of the germ is a:
Recombinant vaccine
Live full germ
Carcinogen
Biofertiliser
Explanation: Recombinant vaccines use only part of the germ — safer.
Question 9 of 16
Treating a genetic disorder by inserting a correct gene is:
Gene therapy
Cloning
Fermentation
Vaccination
Explanation: Gene therapy corrects a faulty gene.
Question 10 of 16
Detecting a disease very early by its genes uses techniques like:
PCR and DNA probes
Boiling
Freezing
Grinding
Explanation: PCR and DNA probes allow early molecular diagnosis.

Question 16 of 16
Animals that have had a foreign gene introduced into them are called:
Transgenic animals
Fossils
Vectors
Hybrids only
Explanation: Transgenic animals carry a foreign gene, e.g. to make medicines in their milk.
