DNA is transcribed into RNA, then codes for proteins, the building blocKs of cells.
But AIDS is the ultimate cybernetic disease;

it changes the normal

DNA- RNA- DNA

loop by imposing its own loop. Where most viruses are DNA, HIV is an RNA virus. With the partnership of reverse transcriptase, it taKes over and alters the DNA transcription process, forcing it to produce more retroviral RNA, then taKes over the DNA in other cells. At the same time, it changes other parts of DNA, encoding for proteins that alter the body's cells, maKing them more receptive to further HIV infection. Finally, the RNA replication cycle is activated by anything that turns on the immune system;

in other words, the immune system destroys itself.

SpooKy and evil disease. Nasty shit.
