Benefits of Virus

Virus always considered detrimental to humans. Hepatitis, dengue fever, and AIDS are examples of deadly diseases caused by viruses. However, the actual virus is not always harmful. So, what benefits the virus?

Virus Definitions

The word virus comes from the same word in Latin, which means 'poison'. Viruses are microorganisms that only consist of genetic material that overwhelmed the protective sheath. The term virus was first used in the 1890s to describe the cause of the disease is smaller than bacteria.

Outside the cell, the virus cannot reproduce, but in living cells the virus can multiply several times and harm its host in the process. There are 3,600 types of virus. Hundreds of them are known to cause a variety of diseases in humans, animals, bacteria, and plants.

Type Virus

Viruses contain DNA or RNA as their genetic material. This could be use for medical purpose, i.e benefits of Herpes simplex virus and hepatitis B virus is a DNA virus. RNA viruses have an enzyme called reverse transcriptase (reverse transcriptase) that a reverse transcription reaction catalysis single stranded RNA into DNA double thread so that the virus could create a version of its own DNA, viruses, including hepatitis C virus and HIV RNA.

Benefits Virus

The study of viruses and their interactions with host cells is an area of major study of molecular biology (a branch of biology that examines life at the molecular scale).

For example, the existence of messenger RNA (messenger RNA), which carries the genetic code from DNA to determine a protein made by the cells, found in bacteriophage research that replicates in bacteria. Bacteriophages are viruses that require a type of bacteria to multiply.

Bacteriophage research is also useful to describe the biochemical factors that begin and end the use of genetic information. Knowledge of how to control the virus replication is useful for understanding the biochemical events at a higher level organism.

The virus is useful as a model system to study the events that control the viral genetic information is actually small pieces of genetic information that is different from the cell's genetic information. This allows scientists to learn multiplication system smaller and simpler, but takes place on the same principle with the host cell.

One major goal of research is to understand the mechanisms of viral replication and the way they control the growth of the virus so that the diseases caused by viruses can be eliminated. Research on viral diseases also contributed much to understanding the body's immune response to the causes of infectious diseases.

Antibodies in the blood serum, as well as secretion of mucous membranes, which helps the body eliminate foreign substances such as viruses, more can be understood by studying the response to viral infection.
The scientists are now concentrating on research to isolate the specific virus genes. These genes can be used in molecular cloning system to produce large amounts of specific viral proteins that can be used as a vaccine.
