11:49 C ( Notes Viruses infect healthy host cells by injecting their genetic material into the host cell and hijacking the cellular machinery of the cell to produce more viruses. Eventually, as the host cell produces more and more copies of the virus, it will explode, releasing the newly produced viruses into the surrounding environment to infect other host cells. Without a host cell, a virus is not capable of replicating itself. Based on the four principles of life discussed in class, are viruses alive? Please justify your answer.
