HIV Virus Copying Itself (IMAGE) University of Southern Denmark Caption In this image, the HIV viruses (big purple balls) are entering a host cell. Once they have entered, they deliver their cargo of viral RNA (purple capsule looking container). The container also carries enzymes needed for the virus to copy itself, and the goal is to inhibit these enzymes so that the virus no longer can copy itself.
