Genetic Engineering and Biotechnology Questions
What is the purpose of genetic engineering in conservation?
-
To create genetically modified organisms (GMOs)
-
To increase the genetic diversity of a species
-
To protect a species from extinction
-
All of the above
B
Correct answer
Explanation
The purpose of genetic engineering in conservation is to increase the genetic diversity of a species so that it is more resistant to disease and environmental change.

What is the process of transferring genetic material from one organism to another?
-
Gene Therapy
-
Genetic Engineering
-
Recombinant DNA Technology
-
Gene Cloning
B
Correct answer
Explanation

What is the process of inserting a foreign gene into a host organism's genome?
-
Transduction
-
Transformation
-
Transfection
-
Gene Editing
B
Correct answer
Explanation
Transformation involves the uptake of foreign DNA by a host organism, resulting in the integration of the new genetic material into the host's genome.
Which organism is commonly used as a host for cloning vectors?
-
E. coli
-
Yeast
-
Human Cells
-
Animal Cells
A
Correct answer
Explanation
E. coli is a widely used host organism for cloning vectors due to its rapid growth, ease of genetic manipulation, and well-studied genetic system.
What is the process of modifying an organism's genome using engineered nucleases?
-
Gene Therapy
-
Genetic Engineering
-
Recombinant DNA Technology
-
Gene Editing
D
Correct answer
Explanation
Gene editing involves the use of engineered nucleases to make precise changes to an organism's genome, allowing for targeted manipulation of genetic traits.
Which ethical consideration is often associated with genetic engineering?
-
Environmental Impact
-
Animal Welfare
-
Genetically Modified Organisms (GMOs)
-
All of the above
D
Correct answer
