According to the shape, viruses can be classified into the following groups
Complex-shaped. The size varies from 10 to 225μm
Cuboid. With a size ranging from 210 to 305 μm.This form is found in cowpox and canary pox viruses.
Rod-shaped represented by the tobacco mosaic virus.
Spherical. With a size ranging from 18 to 150 μm
Viruses can be classified on the
basis of the hosts
Bacterial viruses (bacteriophages)
Living characteristics of viruses
Nonliving characteristics of viruses
1-Adsorption of the virus
3-Blocking of cell information
4-Synthesis of virus components.
5-Release of the virus
