Problem 9: Recombinant DNA 4

Tutorial to help answer the question

"Gene library" is a term used to describe:


Gene library

When the genomic DNA is digested by a restriction endonuclease, and all fragments cloned at random into a plasmid vector, then the majority of genetic information will be included in the mixture of bacteria.

Cultures of the bacteria, with each containing only a fraction of the genome, collectively contain all the genes and are called a library.
