PPT-Virus structure Introduction to virus structure

Outside their host cells viruses survive as virus particles also known as virions The virion is a gene delivery system it contains the virus genome and its functions are to protect the genome and to aid its .

The influenza virus group consists of three enveloped RNA members of the family Orthomyxoviridae:. influenza A, B, and C. . Influenza A . viruses are further classified into hemagglutinin (H) and neuraminidase. In Indiana, the 10-year trend of hepatitis A decreased from 329 cases in 1997 to 33 cases in 2006. Many cases have unknown exposures, while some reported traveling internationally. In A in an element 2. nd. stage.

Virions. can be categorized into four groups according to their structure: icosahedral (enveloped, naked) and helical (enveloped, naked).. Viruses are very small – smaller than the smallest cell.. They are usually surrounded by a capsid of proteins.. For replication, viruses rely on their host cells . ie. ., the cells they infect.. Most viruses exhibit a limited host range- they typically infect only specific types of cells of one host species..
