the overall rate of rna transcription on the giant loops is only about half that on the generality of other loops , and the rna transcribed on the giant loops is computed to have a base ratio of approximately 25 a:39 c:9 g:27 u , implying that there must be about 4 times as many guanine residues on the transcribed as on the non-transcribed strand of the giant loops ' dna .
