What is the rna virus?

Viruses are small cell parasites. They consist simply of a small piece of genetic material, either ribonucleic acid (RNA) or deoxyribonucleic acid (DNA), encapsulated by protein sheath. All viruses try to attack the core of compatible cells to replicate. The genetic material contained in the virus determines the mechanics of how the infected cell is forced to produce new viral cells. The RNA virus is classified on the basis of the type of genetic material that carries and how it directs the host cell to replication.

and the virus remains inactive until it enters the host organism cell. After it is inside, the virus takes control of the host genetic material and uses the natural process of replication of the cell to form copies of yourself. Copies are then released into the body where other cells infect, allowing the virus to spread rapidly throughout the body. Host cells are usually destroyed when copies are released, although an an an an anometime remains viable as a carrier cells inaddiction to the virus.

The difference between DNA and RNA virus is based on the type of genetic material found in a viral capsule or virion before it connects to the host cell. After the host, DNA and RNA viruses are kidnapped by the cell differently, depending on what type they are. DNA viruses, such as Varicella-Zoster that cause chickenpox, attach to the host DNA, which is then converted to Messenger RNA to start the replication process. Most RNA viruses, on the other hand, skip the DNA step and immediately direct infected cells to start replication of viral cells.

Retroviruses, such as human immunodeficiency virus, are the type of RNA virus that is programmed to change the DNA host cells to integrate it. This allows infected cells to function normally until there is time for the cell to naturally replicate, take over and copy the virus in which point. These virusY are particularly problematic because they can remain latent for many years, during which an infected person may not know that he will seek treatment and can spread the virus to others.

common RNA viruses include flu, measles, mumps and West Nile virus. Viruses consist only of a small piece of genetic code and protein coat, so they do not respond to drugs that are designed to kill them, such as antibiotics. Vaccines, on the other hand, can often prevent them from replication and spread to neighboring cells, especially if they are served before the virus has made too many copies.

Some retroviruses are strongly correlated with cancer. For example, leukemia occurs in a large number of people infected with human T-lymphotropic virus. This observation, combined with the fact that viruses can trigger cells to replicate uncontrollably, some of the scientists have led to exploring that the possibility of that, the RNA virus can cause at least some cancer.
