Microbial Genetics

Microbial genetics studies the genetics of very small (micro) organisms; bacteria, archaea, viruses and some protozoa and fungi.This involves the study of the genotype of microbial species and also the expression system in the form of phenotypes. In microorganisms, several kinds of recombination are known to occur. The most common form is general recombination, which usually involves a reciprocal exchange of DNA between a pair of DNA sequences. It occurs anywhere on the microbial chromosome and is typified by the exchanges occurring in bacterial transformation, bacterial recombination, and bacterial transduction.
