The 65-nucleotide leader on the cloned bovine coronavirus defective interfering (DI) RNA, when marked by mutations, has been shown to rapidly convert to the wild-type leader of the helper virus following DI RNA transfection into helper virus-infected cells. A model of leader-primed transcription in which free leader supplied in trans by the helper virus… CONTINUE READING
