I believe you are using the term correctly. From my experience, if you
connect a cDNA to a promoter and then make transgenic animals
expressing the cDNA, you can safely call that a cDNA minigene, or just
a minigene. If there are introns included, the term minigene may not be

You may want to define the term somewhere in your grant, just to be
