RNA based Viruses

Hi I would like to have the information about the RNA virus as well as the Characteristics of the RNA virus?

[shikha]

A RNA virus is an infection that has RNA (ribonucleic corrosive) as its hereditary material. This nucleic corrosive is normally single-stranded RNA (ssRNA) however might be twofold stranded RNA (dsRNA). Notable human illnesses brought about by RNA infections incorporate Ebola hemorrhoragic fever, SARS, the regular frosty, flu, hepatitis C, West Nile fever, polio and measles.

The ICTV characterizes RNA infections as those that have a place with Group III, Group IV or Group V of the Baltimore arrangement of ordering infections and does not consider infections with DNA intermediates throughout their life cycle as RNA viruses.[3] Viruses with RNA as their hereditary material however that incorporate DNA intermediates in their replication cycle are called retroviruses, and involve Group VI of the Baltimore characterization. Outstanding human retroviruses incorporate HIV-1 and HIV-2, the reason for the ailment AIDS.

Another expression for RNA infections that unequivocally avoids retroviruses is ribovirus.

Characteristics

Single-stranded RNA infections and RNA Sense

RNA infections can be further arranged by sense or extremity of their RNA into negative-sense and positive-sense, or ambisense RNA infections. Positive-sense viral RNA is like mRNA and in this manner can be promptly interpreted by the host cell. Negative-sense viral RNA is reciprocal to mRNA and along these lines must be changed over to positive-detect RNA by a RNA polymerase before interpretation.

Double-stranded RNA infections

The twofold stranded (ds)RNA infections speak to a different gathering of infections that shift broadly in host go (people, creatures, plants, parasites, and microscopic organisms), genome fragment number (one to twelve), and virion association (T-number, capsid layers, or turrets). Individuals from this gathering incorporate the rotaviruses, prestigious internationally as the most widely recognized reason for gastroenteritis in youthful kids, and picobirnaviruses, famous worldwide as the most normally happening infection in fecal specimens of both people and creatures with or without indications of looseness of the bowels.
