Provide protection to the nucleic acid against the environment - e. g. nucleases etc. Function in receptor recognition - targeting a virus to a susceptible host and cell type. Surrounding this coat there may be a lipid envelope - this envelope is derived from one of the cell membranes and is not determined by the virus. There may be some modification to the lipid composition induced during virus maturation.
