The retrovirus HIV

This is an envelope virus. The virus is 90-100 nm in size by an outer membrane (lipid bilayer) environments, are incorporated into the glycoprotein spikes. In the outer membrane is a further shell, the capsid, a helical protein structure that surrounds the nucleic acid core, which contains the genome, that the series is to single-out two (2) copies of RNA and contains 7000-11000 nucleotides. The single-stranded RNA

(genetic material) of the retrovirus is transcribed by the enzyme reverse transcriptase (RT) to DNA and integrated into the genome of the host cell.
