Describe what a gene library is.

A gene library is specifically defined as a collection of DNA fragments that represents the entire genome of an organism. This collection is constructed by isolating and cloning segments of DNA, typically in a vector such as a plasmid. The purpose of creating a gene library is to preserve and provide access to the genetic material of the organism, allowing researchers to study specific genes and their functions.

This concept is fundamental in genetic research and biotechnology, as it enables scientists to explore genetic variations, identify gene functions, and develop applications in medicine, agriculture, and other fields. By providing a comprehensive representation of an organism's genetic material, a gene library serves as a crucial resource for various experiments, including gene expression studies and the production of recombinant proteins.
