Essential Biochemistry - Genetic Engineering (Section 2 - No. 12)

What is the primary difference between a genomic DNA library and a cDNA library?

Genomic libraries contain all DNA sequences, while cDNA libraries contain only coding sequences.

Genomic libraries are made using PCR, while cDNA libraries are made using reverse transcriptase.

Genomic libraries are more stable than cDNA libraries.

cDNA libraries include introns while genomic libraries do not.

Genomic libraries include all sequences, while cDNA libraries represent only the expressed genes.
