Summary – Virus
A virus, in the field of biology, is a unique infectious agent that blurs the line between living and non-living entities. These submicroscopic entities consist of genetic material, DNA or RNA, encased in a protein coat, and some may have an outer lipid envelope. Viruses lack the cellular machinery found in living organisms and rely on host cells for replication. They are known for causing various diseases in humans and other organisms, including examples like HIV, Coronavirus, and Ebola.
In this article, you’ve learned about the nature of viruses, their characteristics, structure, and their pivotal role in diseases. Viruses are considered connecting links between the living and non-living, as they depend on host cells for their reproduction.
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.
