what are advantages and disadvantages of virus in human body
3 points of both pls
Answers
Viruses like the bacteriophages have an important function in marine ecology and carbon cycling.
The bacteriophages in the sewage have the ability to systematically decompose the high bacterial level.
Viruses are important in the field of molecular and cell biology. Viruses provide simple system that can be used to manipulate and investigate the functions of cells.
Viruses have provided valuable information about the aspects of cell biology.
For example: viruses have been useful in the study in the genetics and molecular genetics like DNA replication, RNA processing, transcription, translation protein transport and immunology.
In genetics viruses are used ad vectors to introduce genes in the cell which are the case of study.
Virotherapy is another use of virus where they are used as vectors to treat various diseases.
They are used in the treatment of cancer and in gene therapy.
Because of their shape, size and defined chemical structures viruses are used as templates for organizing materials on a nanoscale.
AS viruses can cause devastating epidemics they can be weaponised for biological warfare.
Viruses are used in gene therapy, they are used to genetically manipulate somatic cells of individuals and they are used in production of transgenic plants and animals.
Viruses are used as vector systems for ex vivo gene therapy as they can target cells in less accessible areas of the body.
Disadvantages of Virus:
In humans viruses causes a wide range of diseases which include HIV, chickenpox, influenza, avian flu, cold, sores, and common cold. The strength of the virus is denoted by its virulence.
Some viruses can cause chronic infections; like the virus can replicate the entire life of the host although there is the presence of the host's defense mechanisms. This sort of syndrome is common in Hepatitis viral infection and in HIV.
Hosts with chronic viral infections can be carriers of infectious viruses as long as they live.
Viruses can be transmitted from horizontally, i.e., from person to person, like from mother to child.
They can be vertically transmitted like in the cased of hepatitis B and HIV.
Viruses can cause cancer in humans and other species. Viruses that cause cancers in humans are included in the genotypes of human papillomavirus, hepatitis B virus.
