Molecular microbiology deals with molecular mechanisms and physiological processes of microbes and their utilization in production of biotechnology products and medicines such as vaccines, antibodies. It also involves advancement in pathogenicity of microbes. Molecular microbiology deals with the studies in microbial sciences, assessing the results of molecular studies of eukaryotic microorganisms and of prokaryotes such as bacteria and archaea and their viruses. It further studies genetic, biochemical, biophysical, bioinformatic and structural analysis leading to a deeper understanding of the molecular principles underlying basic physiological processes or mechanisms in molecular biology and microbial genomics.
