What is the main difference between enveloped and nonenveloped viruses? How does this affect entry of each type of virus into the host cells? Variances are expressed.
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.
