Retrovirus structure, animation. The virion (virus particle) has an outer lipid envelope that contains glycoprotein spikes (green). The envelope encloses a protein nucleocapsid (white). Inside the nucleocapsid are two RNA (ribonucleic acid) molecules (red) associated with two reverse transcriptase enzymes (yellow). Reverse transcriptase is used to make a DNA (deoxyribonucleic acid) copy of the virus' RNA genome in an infected cell. | |
