Structures found in the HIV RNA genome as identified by University of North Carolina (UNC) researchers are shown in this handout photograph, obtained by Reuters on August 5, 2009. A new technique has given researchers a "big picture" look at the genome of the AIDS virus, the first time its entire gene map has been decoded, they said on Wednesday. Spheres indicate individual RNA nucleotides. Approximately 2000 nucleotides of the 10,000 nucleotide long HIV genome are shown.
