False-colour transmission electron micrograph of AIDS virus particles inside a stricken T4 lymphoc- yte,a white blood cell of the immune system. AIDS (Acquired Immune Deficiency Syndrome) destroys T4 lymphocytes,rendering the victim liable to fatal secondary infections. The virus,designated HIV for Human Immunodeficiency Virus,is a retrovirus: its genetic program is held in RNA (red cores of virus spheres),translated into DNA inside the T4 cell,& infiltrates the cell's own DNA. Once activated,the viral DNA replicates & progeny bud from the cell wall,killing the host cell. Magnif- ication: x30,000 at 35mm,x60,000 at 6x7cm sizes | |
