Question

A ______ is a foreign gene artificially transferred into an organism.

Answer 1

A transgene is a foreign gene artificially transferred into an organism.

Explanation:

When such a foreign gene is introduced into the genome of an organism like a bacterium, the organism becomes transgenic. For example, in recombinant DNA technology, human insulin genes are transferred into the bacterium E. coli to produce insulin. This process enables the bacterium to express the foreign gene and produce the desired protein, such as insulin, effectively demonstrating the role of a transgene in genetic engineering.
