PPT-Layer # 1: What is a Virus?

A small nonliving particle that invades and then reproduces inside a living cell Biologists consider viruses to be nonliving because viruses are not cells Do not meet all characteristics of living organism. By Ron Sadovsky, Alex Shen, Jacob Levy, and Ethan Kalisky . What is a computer virus?. A computer virus is a program that when operated: . duplicates itself . infects the computer’s other programs, files, or hard drive. . Viroid. . Plant Pathogens. Kenneth L. Johnson II.

In order to survive, viruses must be able to do the following:. 1. Find a host cell it can replicate in. 2. Bind to that cell. 3. Enter the cell. 4. Release its genome in order to replicate.

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. RNA virus. of the family . Orthomyxoviridae. that is responsible for the infectious disease . influenza. (or most commonly referred to as flu) in birds, various mammals (such as pigs) and humans. Typically, influenza is characterized by fever, sore throat, chills and other non-specific symptoms, it is a much more severe disease. It is spread around the world in seasonal epidemics and according to World Health Organization, these annual epidemics result in about three to five million cases of severe illness, and about 250 000 to 500 000 deaths.. 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..
