| Description: a) Electron micrograph of the human immunodeficiency virus (HIV) that is responsible for AIDS. b) A schematic model of HIV. The surface protein gp160 is composed of two fragments, gp41 and gp120. The RNA genome is transcribed into DNA by an error-prone reverse transcriptase. This DNA integrates into the host cell genome, and is then retranscribed to produce new viral RNA. c) False-color scanning electron micrograph of budding HIV-1 virus particles (green spheres) on the surface of a human lymphocyte (red).
