What is the primary purpose of the US Food and Drug Administration (FDA) in regulating genetic engineering?
-
To ensure the safety and efficacy of genetically engineered food and drugs
-
To protect intellectual property rights related to genetic engineering
-
To promote the development of genetic engineering technologies

To regulate the environmental impact of genetic engineering
A
Correct answer
Explanation
The primary purpose of the US Food and Drug Administration (FDA) in regulating genetic engineering is to ensure the safety and efficacy of genetically engineered food and drugs. The FDA evaluates the safety of genetically engineered food and drugs through a rigorous review process before they can be marketed.
What is the term used to describe the unauthorized release of a genetically modified organism (GMO) into the environment?
-
Gene escape
-
Genetic contamination
-
Transgene dispersal
-
Horizontal gene transfer
A
Correct answer
Explanation
Gene escape is the term used to describe the unauthorized release of a genetically modified organism (GMO) into the environment. Gene escape can occur through various mechanisms, such as cross-pollination, seed dispersal, or accidental release during transportation or cultivation.
What is the term used to describe the process of modifying an organism's genome using genetic engineering techniques?
-
Genetic manipulation
-
Gene editing
-
Transgenesis
-
Recombinant DNA technology
A
Correct answer
Explanation
Genetic manipulation is the term used to describe the process of modifying an organism's genome using genetic engineering techniques. Genetic manipulation can be used to insert, delete, or modify genes in an organism's genome.
What is the term used to describe the process of transferring genetic material from one organism to another?
-
Gene transfer
-
Genetic engineering
-
Transgenesis
-
Recombinant DNA technology
A
Correct answer
Explanation
Gene transfer is the term used to describe the process of transferring genetic material from one organism to another. Gene transfer can occur naturally through mechanisms such as sexual reproduction or viral infection, or it can be performed artificially using genetic engineering techniques.
