Describe the makeup of viruses
WebThere are two categories of viruses based on general composition. Viruses formed from only a nucleic acid and capsid are called naked viruses or nonenveloped viruses. Viruses formed with a nucleic-acid packed capsid surrounded by a lipid layer are called enveloped viruses (see Figure 6.5 ). WebA simple sketch of a virus: nucleic acid genome, surrounded by a protein coat (capsid), additionally surrounded by a membrane (envelope) There are all sorts of virus shapes and sizes. However, all virus particles have a protein coat that surrounds and protects a nucleic acid genome. This protein coat is called a capsid, and the instructions for ...

WebEncapsulating the RNA genome is the viral envelope (teal), which protects the virus when it is outside of a host cell. This outer envelope is made from a layer of lipids, a waxy barrier containing fat molecules. As well as protecting the precious genetic cargo, this layer anchors the different structural proteins needed by the virus to infect cells.
