...outer membrane to the nucleus. The virus hitches a ride aboard a multi-unit protein called dynein, commonly referred to as a molecular motor. "Dynein is like a tractor trailer, the microtubules are the highway, and the HIV particles are the cargo," said David McDonald, assistant professor of microbiology ...Deer flies a biting problem?
