we conclude from these results that in isolated nuclei of these mammalian cells rna polymerase iii starts transcription of 5s rna gene at the same site as the 5 ' end of mature 5s rna , proceeds toward the 3 ' direction and stops at a site probably 8 nucleotides downstream from the 3 ' end of mature 5s rna .
