experiments using leader rna fragments , a vsvind cdna derived from the 3 ' end of the genome , and synthetic oligodeoxynucleotide homologous to regions of the vsv leader indicated that the au ( at ) -rich center region of the vsv leader molecule is sufficient to inhibit dna-dependent transcription directed by both polymerase ii and iii , but flanking nucleotide sequences are important for more efficient inhibition of transcription .
