Each person's gut carries a different collection of bacteria-infecting viruses that may benefit their hosts, researchers report. The viruses contain DNA fragments whose functions include cell repair and food processing.
This 3D animation shows how HIV infects cells, and how HIVs replicate themselves using infected cells' materials. At the end of the video, possible ways to inhibit HIV infection/replication is illustrated.

The RNAi mechanism is explained in two ways...
