Since viruses are not cells, they are structurally much simpler than bacteria. An intact infectious viral particle - or virion - consists of a genome, a capsid, and maybe an envelope.

An intact infectious viral particle - or virion - consists of a genome, a capsid, and maybe an envelope. Viruses possess either DNA or RNA as their genome. The genome is typically surrounded by a protein shell called a capsid composed of protein subunits called capsomeres.
