Solution:
A transgenic, or genetically modified, organism is one that has been altered through recombinant DNA technology, which involves either the combining of DNA from different genomes or the insertion of foreign DNA into a genome.
One example of this procedure is a GloFish that is a type of transgenic zebrafish that has been modified through the insertion of the green fluorescent protein gene.
Thus according to the problem, we can conclude that the correct answer is:
If you were to insert the gene for bioluminescence, it would be a transgenic organism.
