Types of Viruses

Here are some structures of these viruses' shapes

- Polyhedral

- Spherical

- Helical

- Complex

Polyhedral

One example of this structure is the adenovirus. It uses its pentons or the extended arm like protein, to bind to the receptors on the cell membrane. Once attached, as it gets pulled in, it breaks through the membrane and releases the viral DNA

Spherical

An example of a spherical virus, would be the flu. It would bind to the cell membrane of a cell, then enter the cell releasing RNA to replicate protein for more viruses

Helical

Tobacco mosaic virus is helical structured virus. Once it enters a plant, the virus breaks up into many TMV RNA and infect more cells.

Complex

Complex viruses are like Bacteriophage. They land on the surface of cells and inject the viral genome into the cell.
