Document Summary

Organisms too small to be seen clearly by the unaided eye. Consists of a single cell or cell cluster, or a virus. The study of microbes (microorganisms) and their interactions with other living organisms. Understanding the nature and functioning of the microbial world. Uses microbial cells to understand fundamental processes of life. Applying our understanding of the microbial world for the benefit of humankind and planet earth. At the forefront of medicine, agriculture, and industry. Genome is usually a single closed circular chromosome (nucleoid, additional small circles of dna called plasmids) Genome organized into linear chromosomes (contained in membrane-enclosed nucleus, & genome is typically larger) Cytoplasmic membrane that separates the inside of the cell from the outside. Cytoplasm containing an aqueous mixture of macromolecules, small organic molecules, and ions. Most microorganisms contain a cell wall that provides structural strength. First sequences genome was h. influenzae in 1995: cole genome is a fairly typical prokaryotic genome.
