Question

Which best describes a transgenic organism?

पर्याय

• One that acts as the donor for DNA to be moved into another organism

• One produced by cloning a mutant cell

• One that contains a foreign gene and is free-living in the environment

• Any genetically modified organism resulting from laboratory research

Answer 1

One that contains a foreign gene and is free-living in the environment

Explanation:

A transgenic organism is one in which a foreign gene has been artificially transferred into its genome, enabling it to express new traits. This foreign gene is introduced via recombinant DNA technology and is incorporated so that the organism can live and reproduce with this new genetic information. For example, bacteria engineered to produce human insulin are transgenic organisms. This definition distinguishes transgenic organisms from merely genetically modified ones that may not be free-living or contain foreign genes in a stable way.
