Why has E.coli become a commonly used model organism in genetic research?

Accepted Answer

This organism can be cultured in the laboratory on a simple medium,it is amenable to all sorts of biochemical analyses,and mutant strains with different growth requirements can be isolated easily.E.coli cells and the viruses that infect them are tiny creatures that can be cultured in the laboratory to produce tens of billions of their own kind in a short period of time.These large population sizes allow researchers to screen efficiently for rare events such as the occurrence of a particular kind of mutation.
