The virus that possesses RNA as genetic material is called RNA virus. They can either be a single-stranded or a double-stranded RNA. Some of the diseases caused by the RNA virus to humans include common cold, hepatitis, polio, West Nile fever, influenza, SARS, and measles. All plant viruses are examples of the RNA virus.
Mutation rates are higher for the RNA virus. Therefore, it may be considered as a one of the main reason for lacking back in preventing effective vaccines to treat and prevent certain viral diseases.
Double-stranded RNA virus comprises of distinct virus that differs widely based on host-virus such as fungi, bacteria, genome, virion, and organization.
A single-stranded RNA are categorized based on senses that are positive sense or negative sense.
- Positive-sense RNA is similar to mRNA. They are usually translated into host cells.
- Negative-sense RNA must be converted into positive sense RNA before translation using RNA polymerase.
