RNA VIRUSES Meaning and
Definition
-
RNA viruses are a type of virus that possess ribonucleic acid (RNA) as their genetic material. RNA is a single-stranded nucleic acid molecule that carries genetic information and is essential for protein synthesis. RNA viruses differ from DNA viruses, which have deoxyribonucleic acid (DNA) as their genetic material.
RNA viruses have a diverse range of structures and sizes, but they all share the characteristic of having RNA as their genome. They infect various organisms, including plants, animals, and humans, and can cause a wide range of diseases. Examples of RNA viruses include the influenza virus, the human immunodeficiency virus (HIV), the hepatitis C virus, measles virus, and the Ebola virus.
RNA viruses replicate within host cells by hijacking the host's cellular machinery, including enzymes involved in transcription and translation. They typically have a high mutation rate due to the lack of proofreading mechanisms in their RNA replication process. This high mutation rate allows RNA viruses to evolve rapidly, leading to the emergence of new strains and variants.
RNA viruses are further classified into different families based on their genetic characteristics, replication strategies, and other factors. Examples of RNA virus families include Flaviviridae, Orthomyxoviridae, and Coronaviridae.
Understanding RNA viruses is crucial for developing vaccines, antiviral drugs, and diagnostic tests to control and prevent their spread.

Etymology of RNA VIRUSES
The etymology of the term "RNA viruses" can be understood by examining the individual components of the phrase.
1. RNA: RNA stands for Ribonucleic Acid. It is a type of nucleic acid that plays a crucial role in the synthesis of proteins and serves as the genetic material for some viruses. The term "RNA" was coined by the American molecular biologist, James Watson, in 1960. It was derived from the initial letter "R" for "Ribonucleic" and the abbreviation "NA" for "Nucleic Acid".
2. Viruses: The word "virus" comes from Latin and means "poison" or "sap of plants". It was originally used to describe harmful substances produced by living organisms that caused diseases. In the late 19th century, the term was extended to include microscopic infectious agents that reproduce inside host cells.
