Each viral particle, or virion , consists of genetic material, DNA or RNA , within a protective protein coat called a capsid . The capsid shape varies from simple helical and icosahedral (polyhedral or near-spherical) forms, to more complex structures with tails or an envelope . Viruses infect cellular life forms and are grouped into animal, plant and bacterial types, according to the type of host infected. Biologists debate whether or not viruses are living organisms. Some consider them non-living as they do not meet the criteria of the definition of life . For example, unlike most organisms, viruses do not have

4. Introduction To The Viruses This was the first clue to the nature of viruses, genetic entities that lie somewhere in the grey area between living and nonliving states. http://www.ucmp.berkeley.edu/alllife/virus.html

Introduction to the Viruses In 1898, Friedrich Loeffler and Paul Frosch found evidence that the cause of foot-and-mouth disease in livestock was an infectious particle smaller than any bacteria. This was the first clue to the nature of viruses, genetic entities that lie somewhere in the grey area between living and non-living states. Viruses depend on the host cells that they infect to reproduce. When found outside of host cells, viruses exist as a protein coat or capsid , sometimes enclosed within a membrane. The capsid encloses either DNA or RNA which codes for the virus elements. While in this form outside the cell, the virus is metabollically inert; examples of such forms are pictured below. Viral micrographs : To the left is an electron micrograph of a cluster of influenza viruses, each about 100 nanometers (billionths of a meter) long; both membrane and protein coat are visible. On the right is a micrograph of the virus that causes tobacco mosaic disease in tobacco plants. When it comes into contact with a host cell, a virus can insert its genetic material into its host, literally taking over the host's functions. An infected cell produces more viral protein and genetic material instead of its usual products. Some viruses may remain dormant inside host cells for long periods, causing no obvious change in their host cells (a stage known as the

Even such a simple virus is dangerous because it will quickly use all available memory and bring the system to a halt. An even more dangerous type of virus is one capable of transmitting itself across networks and bypassing security systems.

StumbleUpon Del.icio.us In computers, a virus is a program or programming code that replicates by being copied or initiating its copying to another program, computer boot sector or document. Viruses can be transmitted as attachments to an e-mail note or in a downloaded file, or be present on a diskette or CD. The immediate source of the e-mail note, downloaded file, or diskette you've received is usually unaware that it contains a virus. Some viruses wreak their effect as soon as their code is executed; other viruses lie dormant until circumstances cause their code to be executed by the computer. Some viruses are benign or playful in intent and effect ("Happy Birthday, Ludwig!") and some can be quite harmful, erasing data or causing your hard disk to require reformatting. A virus that replicates itself by resending itself as an e-mail attachment or as part of a network message is known as a worm Generally, there are three main classes of viruses:

For Educators What is a computer virus? Published: October 23, 2006 Computer viruses are small software programs that are designed to spread from one computer to another and to interfere with computer operation. A virus might corrupt or delete data on your computer, use your e-mail program to spread itself to other computers, or even erase everything on your hard disk. Viruses are most easily spread by attachments in e-mail messages or instant messaging messages. That is why it is essential that you never open e-mail attachments unless you know who it's from and you are expecting it. Viruses can be disguised as attachments of funny images, greeting cards, or audio and video files. Viruses also spread through downloads on the Internet. They can be hidden in illicit software or other files or programs you might download. To help avoid viruses, it's essential that you keep your computer current with the

Viruses are strange things that straddle the fence between living and non-living. On the one hand, if they're floating around in the air or sitting on a doorknob, they're inert. They're about as alive as a rock. But if they come into contact with a suitable plant, animal or bacterial cell, they spring into action. They infect and take over the cell like pirates hijacking a ship. What They Are The polio virus T4 bacteriophage Adenovirus , right. Courtesy of Brookhaven National Laboratory. VIRUSES OF NOTE Adenoviruses are used in experimental gene therapy treatments to deliver therapeutic genes. Bacteriophages are being explored as tools to treat bacterial infections by targeting and destroying infectious bacteria. Human Immunodeficiency Virus (HIV) is responsible for the AIDS pandemic. Human papillomavirus causes cervical cancer. Influenza causes the flu, which killed some 21 million people worldwide in 1918. Lambda phage is useful in cloning DNA.
