despite the high genomic copy number for the 5 s rrna gene , under optimized conditions as much as 80 % of the cellular 5 s rna can be mutant , and rna structure analyses indicate that some of these rnas can readily be assembled into the ribosome structure resulting in an in vivo ribosome population which is also approximately 80 % mutant .
