You've got your radiator, ratty, throttle, body rats, mission differ, rats, strats, top rat, thermos rat traction and control, and your lytic converter.
When the virus enters into the lytic phase, thousands of virus particles can be made from a single cell which can destroy the cell and subsequently infect neighboring cells.
In the lytic phase, the virus starts to replicate, so its DNA gets transcribed and translated by cellular enzymes, in order to form viral proteins, which are packaged into new viruses.
