Viruses infect all types of life forms, from animals and plants to microorganisms, including bacteria and archaea. Once inside the host cell's cytoplasm, the virus uses its own reverse transcriptase enzyme to produce DNA from its RNA genome, the reverse of the usual pattern, thus retro (backwards). Most carcinogens, singly or in combination, produce. The primary infection is usually asymptomatic, but may produce mononucleosis symptoms similar to those produced by primary infection with HIV. A typical example is the herpes virus, which tends to hide in nerves and become reactivated when specific circumstances arise. More recently, scientists have discovered a new type of virus, called a mimivirus. Viruses possess unique infective properties and thus often cause disease in host organisms.
