The central figure on the home page depicts a cross section of a retroviral
virion, surrounded by images representing the research interests of the HIV Dynamics and Replication Program (HIV DRP). The oval images around the virion link to the home pages of the Program's senior scientific
staff (clockwise from the top):
Three-dimensional structures of the following virion proteins are shown along the left side of HIV DRP home page:
(from the top) reverse transcriptase; protease; integrase; the Gag proteins nucleocapsid,
capsid, and matrix; and the gp120 envelope protein. The colors of the structures
correspond to the colors of the same components shown in the virion.
