Document Summary

A virus particle, or virion , consists of the following: Nucleic acid --genetic instructions, either dna or rna , either single-stranded or double-stranded (never both dna and rna, only either or). Coat of protein --surrounds the dna or rna to protect it. Lipid membrane --surrounds the protein coat (found only in some viruses, including influenza; enveloped viruses as opposed to naked viruses). Atoms small molecules proteins viruses prokaryotes eukaryotes. Family sub-family genus species. There are various different species of hiv. Viruses do not want to kill the host; the longer the virus can stay in the host, the more successful the virus is. This way, it can be easily transmitted. Lentiviruses are transmitted as enveloped rna viruses. A capsid protein is surrounding the nucleic acid. Glycoproteins come out of this, so it can connect to things in to body. Upon target cell entry, viral rna is converted to dsdna by a virally encoded reverse transcriptase present in the virus particle.
