HIV infected T-cell. Coloured scanning electron micrograph of HIV viruses (white dots) budding from the cell membrane (blue) of an infected T- lymphocyte,a key cell of the human immune system. The AIDS virus known as HIV (Human Immuno- deficiency Virus) has genetic material in the form of RNA. It possesses an enzyme,reverse transcriptase,which enables it to subvert the DNA genetic material of the T-cell in order to replicate more viruses. Progeny of the HIV virus then bud away from the cell membrane of the host T-cell,which is ultimately destroyed. Destruction of the immune system renders AIDS victims liable to a number of fatal secondary infections | |
