Schematic representation of HIV-1 genome organization. The three coding reading frames are depicted along with their open reading frames (rectangles). Genome position is numbered according to HXB2 ...

Paul Sharp and colleagues from the University of Nottingham Queens Medical Centre in England compared full-length genome sequences of chimpanzee HIV strains with inferred ancestral sequences for three ...

HIV-1, like other viruses ... Another important discovery was an intricate RNA structure near the critical "frameshift site" in the viral genome. This frameshift site is essential for the virus ...

This way DNA can reproduce itself without changing its structure -- except for occasional errors, or mutations. The structure so perfectly fit the experimental data that it was almost immediately ...
