RNA virus

RNA viruses can be further classified according to the sense or polarity of their RNA into negative-sense and positive-sense RNA viruses. Positive-sense viral RNA is identical to viral mRNA and thus can be immediately translated by the host cell.

An RNA virus is a virus that either uses RNA as its genetic material, or whose genetic material passes through an RNA intermediate during replication.

RNA viruses occur in four distinct groups:
Those with a genome that consists of single-stranded antisense RNA; that is, RNA that is the complement of the message sense. This is also called negative-stranded RNA. Examples: measles, Ebola [Link] ...

HIV is an enveloped RNA virus: As HIV buds out of the host cell during replication, it acquires a phospholipid envelope. Protruding from the envelope are peg-like structures that the viral RNA encodes.
