What is also amazing about HIV is its viral complexity and ability to constantly mutate. As a result it is proving to be difficult to observe and understand, let alone to find ways of destroying it:
The genome of a single-strand RNA virus such as HIV, which comprises only 10,000 nucleotides, is small and simple compared with that of most cells. Yet from a molecular standpoint, it is unimaginably complex. Each of those nucleotides contains one of four possible bases: adenine, uracil, guanine or cytosine. The unique sequence specified by the genome of HIV therefore represents just one choice out of 4 10,000 possibilities -- a number roughly equivalent to a one followed by 6,000 zeroes (Eigen, 1993 p. 42).
