1. Which of the following is NOT a feature of genetically modified
crops developed through biotechnology?
A. Herbicide resistance
B. Pest resistance
C. Increased shelf life
D. Reduced photosynthesis
Answer: d) Reduced photosynthesis
Rationale: Genetically modified crops are typically designed to improve
characteristics such as herbicide resistance, pest resistance, and shelf
life, not to reduce photosynthesis.
2. What is the purpose of Bt protein in genetically modified crops?
A. To promote faster growth
B. To increase resistance to drought
C. To protect plants from insects
D. To enhance nutrient absorption
Answer: c) To protect plants from insects
Rationale: Bt protein, produced by genetically modified crops like Bt
cotton, provides resistance to certain insect pests by producing toxins
that are harmful to these pests.
3. Which of the following is NOT a primary objective of agricultural
biotechnology?
,A. Increased crop yield
B. Reduced use of pesticides
C. Creation of genetically modified crops
D. Increased water usage in farming
Answer: d) Increased water usage in farming
Rationale: The primary objective of agricultural biotechnology is to
increase crop yields, reduce pesticide use, and create genetically
modified crops. Increasing water usage is not a goal of biotechnology.
4. What is the process of introducing a new gene into a plant cell
called?
A. Transcription
B. Transformation
C. Translation
D. Replication
Answer: b) Transformation
Rationale: Transformation refers to the process of introducing foreign
genes into a plant cell, typically using methods like Agrobacterium-
mediated transformation or biolistics.
5. Which gene editing technique is known for its ability to precisely
alter specific genes in plants?
A. CRISPR-Cas9
B. Agrobacterium-mediated transformation
C. Electroporation
, D. Southern blotting
Answer: a) CRISPR-Cas9
Rationale: CRISPR-Cas9 is a gene-editing tool that allows for precise
alterations to the DNA of plants, enabling researchers to target specific
genes with great accuracy.
6. Which of the following is an example of a genetically modified crop
that is designed to resist pests?
A. Bt cotton
B. Golden rice
C. Roundup Ready soybeans
D. Golden potatoes
Answer: a) Bt cotton
Rationale: Bt cotton is genetically modified to express the Bacillus
thuringiensis (Bt) protein, which is toxic to certain pests, reducing the
need for chemical insecticides.
7. What is the main advantage of genetically modified crops that are
tolerant to herbicides?
A. They require less water
B. They increase nutritional value
C. They allow farmers to use herbicides to control weeds without
harming the crops
D. They grow faster
Answer: c) They allow farmers to use herbicides to control weeds
without harming the crops
