When a eukaryotic gene is cloned into a bacterium, the advantage of a complementary DNA (cDNA) gene being used instead of fragments of genomic DNA is that
A. the promoter and terminator are found in the cDNA gene but not in the genomic fragment.
B. the introns have been removed from the cDNA gene but not from the genomic fragment.
C. the cDNA is made with the nucleotides found in the prokaryote but not in the eukaryote.
D. there is no advantage to using a cDNA gene rather than a genomic fragment.
