Importance of Virus
Viruses are known to cause fatal diseases in humans, but they also have significant roles in our daily life. The importance of the virus is outlined as follows:
- Viruse are utilsed to create vaccines which can be injected during the infant phase in humans to prevent diseases.
- Virus do not belong to either the living world nor the non-living world. Hence, they act as connecting links.
- Viruses are studied extensively as they help in understanding various processes that occur in molecular biology such as transcription, replication, immune mechanisms, etc.
- Virus can be used as vectors which help in target delivery of drugs.
- Viruses are thesedays, being used in the process of pest management.
- In nanotechnology, viruses can be utilized as carriers for genetically altered genomes.
Virus in Biology
Virus is an infectious agent of the submicroscopic size that cannot survive alone. Hence, it infects cells of other living organisms and replicates itself using the components of these host cells. Its biological structure is comprised of a fragment of nucleic acid that could either be DNA or RNA. The most commonly known examples of viruses are HIV Virus, Coronavirus, Ebola virus, etc.
In this article, you will learn about what is virus in biology, characteristics of virus, its structure, importance, reproduction and examples of virus.
