plants or animals. B: Viruses: A virus is a small infectious agent‚ too small to be seen by the naked eye. They can’t multiply on their own‚ only inside the cells of other organisms. Viruses consist of genetic material ( DNA or RNA) surrounded by a protective coat of protein. They are capable of latching onto cells and getting inside them. The cells of the mucous membranes‚ such as those lining the respiratory passages that we breathe through‚ are particularly open to virus attacks because they are not

With this information in hand‚ Varmus‚ in the summer of ’69‚ travelled to UC San Francisco where he alongside Mike Bishop would launch their study of the avian sarcoma virus and its transforming properties. Before they could begin their studies however‚ two more very important discoveries were made. The

With more than one-third of the world’s population living in areas at risk for infection‚ dengue virus is a leading cause of illness and death in the tropics and subtropics. As many as 400 million people are infected yearly. Dengue is caused by any one of four related viruses transmitted by mosquitoes. There are not yet any vaccines to prevent infection with dengue virus and the most effective protective measures are those that avoid mosquito bites. When infected‚ early recognition and prompt supportive

These strains are the biological form of the flu‚ and having them in your body they create a stronger immune system. Then your body will be able to fight off infections that are found in those virus strains. The vaccines goes through a process called DNA sequencing where they
