All viruses can be divided into nonenveloped or enveloped, depending upon whether they have a lipid bilayer surrounding their nucleocapsid. This characteristic affects the mode of entry of the virus, since enveloped viruses can fuse to cells and nonenveloped viruses cannot.
Enveloped viruses obtain a lipid bilayer envelope around their nucleocapsid by budding from host cells. Prior to budding, viral glycoproteins are targeted to the cell membrane. When the virus buds, it takes with it a portion ...
Enveloped and nonenveloped viruses are contrasted.
