because influenza viral rna transcription in vitro is greatly enhanced by the addition of a primer dinucleotide , apg or gpg , we have proposed that viral rna transcription in vivo requires initiation by primer rnas synthesized by the host cell , specifically by rna polymerase ii , thereby explaining the alpha-amanitin sensitivity of viral rna transcription in vivo .
