Viruses are groups of acellular organisms that lack their own cell machinery. They have protein coat called capsid which protects the genetic material. The capsid is made up of small units known as the capsomers. The genetic material in viruses is either single stranded or double stranded DNA or single stranded RNA. Viruses have either RNA or DNA as their genetic material.

Bacteria are a type of biological cell. They constitute a large domain of prokaryotic microorganisms. Typically a few micrometres in length, bacteria have a number of shapes, ranging from spheres to rods and spirals. Bacteria were among the first life forms to appear on Earth, and are present in most of its habitats.
