Question

Quizplus · Accepted Answer

Viruses are not living cells, but use the cellular machinery of their hosts to replicate their genetic material, which is made of DNA or RNA. They can act as vectors for horizontal gene transfer between cells of the same or different species. Infection is followed by either lysis (killing of the host cell) or the persistence of the viral genome in the host cell (which can last for many cell generations).
