Microbiology, study of microorganisms, or microbes, a diverse group of generally minute simple life-forms that include bacteria, archaea, algae, fungi, protozoa, and viruses. The field is concerned with the structure, function, and classification of such organisms and with ways of both exploiting and controlling their activities.

There are two main type of transposable elements in bacteria having different size and structure. They are; insertion sequences (is elements) prokaryotic transposons (tn): composite and non-composite transposons. Insertion sequences (is element): is elements are the simplest type of bacterial transposable sequences that can insert at different location of bacterial chromosome and plasmid through illegitimate recombination.
