Structure of an HIV Capsid

This animation shows atoms of the HIV capsid, the shell that encloses the virus's genetic material. Scientists determined the exact structure of the capsid and the proteins that it's made of using a variety of imaging techniques and analyses. They then entered this data into a supercomputer that produced the atomic-level image of the capsid.
