2021-02-04 · Poliovirus is a member of a family of viruses called the Picornaviridae. Virions are spherical in shape with a diameter of about 27nm. The particles are simple in that they are composed of a protein shell surrounding the naked RNA genome.

The virus can infect any mammal, and most die within weeks of infection. Smallpox is a human virus transmitted by inhalation of the variola virus, localized in the skin, mouth, and throat, which causes a characteristic rash. Before its eradication in 1979, infection resulted in a 30–35 percent mortality rate. LESSON 1: VIRUS MORPHOLOGY and ANATOMY Don’t let the word “morphology” scare you. It has a simple meaning. It is the study of the shape of something. That’s right, scientists could have said “let’s look at the shape” but they had to make up a complicated word that uses a Greek word so it would sound more “science-y.” Morphology of Viruses Plant viruses are usually described as 1.

Viruses come in many shapes and sizes, but these features are consistent for each viral family. As we have seen, all virions have a nucleic acid genome covered by a protective capsid. The proteins of the capsid are encoded in the viral genome, and are called capsomeres. 2011-12-01 General Morphology Capsid Structure determines shape: • Helical Viruses = nucleic acid is inside a hollow cylindrical capsid with a helical structure • Rabies, Ebola viruses, Tobacco Mosaic Virus • Polyhedral viruses = many sided; icosahedron is common with 20 equilateral triangles as sides and 12 vertices • Poliovirus, Adenovirus, herpes, • Complex structures • Pox virus & bacteriophage LESSON 1: VIRUS MORPHOLOGY and ANATOMY Don’t let the word “morphology” scare you.

The viral envelope is absent in some viruses, known as nonenveloped viruses. Morphology of virus 1. Viruses are the smallest known infective agents and perhaps the simplest form of life. Viruses do not posses cellular organization and they do not fall strictly in to the category of unicellular microorganism.
