Why Would Researchers Want to Have Both Genomic Libraries and CDNA

question 60

Multiple Choice

Why would researchers want to have both genomic libraries and cDNA libraries from a particular organism?

• B) because a genomic library is generally too big to be helpful, while a cDNA library, being smaller, is much easier to study
• C) because a genomic library will be the same in every cell, while a cDNA library tells researchers which genes are being expressed in individual cell types
• D) because a cDNA library is a lot easier to clone than a genomic library
