Cutaway illustration of an HIV virus

HIV virus. Cutaway illustration of a humanimmuno- deficiency virus (HIV), the cause of AIDS(acquired immune deficiency syndrome). In the coreare two strands of RNA (ribonucleic acid, orange), which carry the viral genes. Associated with theseis the enzyme reverse transcriptase (red), whichinserts the genes into the host cell's DNA(deoxyribonucleic acid). The RNA is enclosed intwo protein coats (blue and mauve) made ofrepeating subunits called capsomeres (spheres).Around these is the membrane, a lipid bilayer(orange), which is studded with GP120glycoproteins (green) that bind to target humanwhite blood cells

AIDS virus particle

AIDS virus particle, artwork. AIDS( acquired immune deficiency syndrome ) is caused by the human immunodeficiency virus (HIV). The outerlayer of this virus particle is a membraneenvelope (green) made from the membrane of thehost cell in which this particle developed. Themembrane encloses an icosahedral matrix layer, which surrounds the inner genetic core (not seen).Knobs (yellow) allow the virus particle to attachto cells. HIV attacks lymphocyte white bloodcells, which play an important role in the immunesystem. This severely impairs the immune system, allowing normally harmless infections to becomelife threatening
