Describe two advantages for cloning a gene from a cDNA library versus a genomic DNA library
What will be an ideal response?
A cDNA library is free of introns and it is enriched for the gene of interest because it is
made from mRNA from the desired tissue type. In contrast, a genomic DNA library still has
introns and it has every gene in the genome, making it more difficult to find the gene of interest.
