Question

A technique utilized by a group of biologists to isolate an antifreeze gene found in cold water species of fish and introduce it into the genome of a different organism is called as ?

• A. Cloning
• B. Artificial selection
• C. Selective breeding
• D. Genetic engineering
• E. Sexual recombination

Answer 1

The correct option is D Genetic engineering

• Genetic engineering is the branch of science which deals with the modification of genes.
• The desired genes are isolated from the host like the gene for antifreeze protein and are inserted into the vectors.
• The vectors carry the foreign gene into the desired organism like the fish and then the gene gets introduced into the genome of fish, resulting in the production of the protein.

Thus, the correct answer is option D.
