Applied Biology


Cellular organization

Life exhibits varying degrees of organization. Atoms are organized into molecules, molecules into organelles, and organelles into cells, and so on. According to the cell theory, all living things are composed of one or more cells, and the functions of a multicellular organism are a consequence of the types of cells it has. Viruses are not classified as cells and therefore are neither unicellular nor multicellular organisms. Most people do not even classify viruses as “living” because they lack a metabolic system and are dependent on the host cells that they infect to reproduce. Viruses have genomes that consist of either DNA or RNA, and there are examples of viruses that are either double-stranded or single-stranded. Importantly, their genomes code not only for the proteins needed to package its genetic material but for those proteins needed by the virus to reproduce during its infective cycle.
