Answer by Bello DNA library is a collection of DNA fragments of one organism, each carried by a plasmid or virus and cloned in an appropriate host. A DNA probe is used to locate a specific DNA sequence in the library. A collection representing the entire genome is called a genomic library. An assortment of DNA copies of messenger RNA produced by a cell is known as a complimentary DNA (cDNA) library. Also called gene library.
