Correct Answer: D. complementary DNA
The genomic library of an organism can be created by using complementary DNA (cDNA). cDNA is synthesized from messenger RNA using reverse transcriptase. Genomic libraries made using cDNA are not complete as the messenger RNA that is transcribed is not an exact complement to the original DNA strand due to the absence of introns.
