<prompt> All of the following are true about genomic library, EXCEPTCollection of cloned DNA fragmentsScreening is done by oligonucleotide probesOnly exons are presentVectors are used to carry and replicate the fragments  <response>: A genomic library is bacteria with plasmids containing DNA fragments representing the majority of the genetic information from a plant or animal. Genomic library cDNA library Genomic DNA isolated from an organism is digested by restriction enzymes and put in separate vectors. mRNA is conveed to cDNA which contains only exons. Each clone contains a fragment of the entire genome exon intron of an organism within a vector. Each clone usually contains an intact gene Appropriate for small genome. Appropriate for large genome.
