Which library should be used, genomic or cDNA when the screening is carried out by oligonucleotide probes? Correct Answer cDNA

If oligonucleotide probes are used, then cDNA libraries should be used. It is so because cDNA libraries are enriched for coding sequences and thus fewer sequences have to be screened.
