What is a gene library?
Gene Library: Several clones of cells each containing one of a few foreign genes are finally obtained, representing almost all the genes of an organism, it is termed the gene library of that organism. From that gene library, it is possible to identify a clone containing the gene of interest. In order to obtain the gene library of an organism, its genome is first to cut into smaller DNA fragments containing one or a few genes, and such fragments can be cloned in the cell where such a cell multiplies to form a group of cells, all cells have same foreign DNA and are termed clone.
