while fura alone had no effect on this resistant cell line , the combination of fura plus inosine altered the levels of ribose 1-phosphate but not 5-phosphoribosyl 1-pyrophosphate , altered the maturation of precursor ribosomal rna by blocking the formation of 18s rna , altered the methylation of the ribosomal rna , and caused inhibition of the growth of these cells .
