This video provides an overview of viruses, explaining what they are and how they can spread. It also highlights some of the most common viruses that affect humans. This information could be useful in fighting these diseases.
00:00:00 A virus is a tiny, organic molecule that is composed of two types of molecules, assembled together to form a protein that encapsulates a section of genetic material-either DNA or RNA. Some viruses also have a fat capsule that helps them survive in the environment outside of cells, but are susceptible to detergents and alcohols.
The description of viruses began 136 years ago with the invention of filtros for isolation. The first virus to be isolated and studied was the virus of the leaves of the workbench.
Currently, there are about 5000 videos of written descriptions and millions without describing and no one knows their evolutionary origin. They could be fragments of stray acid nucleic acids that pass from cell to cell have a average size of 100 times smaller than bacteria-250 nanometers or millionth of a meter. They are only visible with an electron microscope and are not living beings. They are parasites that are obligate of cells-whether these are bacteria protists, fungi, or animal cells-because they use the genetic replication and synthesis of proteins from these cells to multiply. For example, viruses that enter cells exposed to membrane-containing cells such as epithelial cells-that is, cells that cover the body-infect them by injecting their genetic acid
00:05:00 This video explains what viruses are and how they can affect humans. Viruses can be spread through contact with infected people, animals, or plants. They can also be spread through airborne particles and through contact with contaminated surfaces. The video also mentions some of the most common viruses, such as the cold and the flu. The change that will be needed to control global viruses is likely to be proportional to the growth of these diseases. This information could be useful in fighting these diseases.
