a. an example of a transgenic tomato (also called GMO tomato)
Explanation:
Genetic modification is the process by which an organim's genome is manipulated in order to achieve a desirable feature in such organism. Also called genetic engineering, genetic modification involves using biotechnology to alter an organims genetic composition. The organism whose genome is manipulated is called GENETICALLY MODIFIED ORGANISM (GMO) or TRANSGENIC ORGANISM.
In this case, a tomato with a gene from a fish that helps the tomato resist frost damage is said to be an example of GMO or transgenic organism because the genome of the tomato plant has been manipulated by inserting a desirable gene (resistance to frost) into it.
