since published values on the relative lengths of qbeta rna and several other homogeneous rnas ( e. coli 23s rrna , e. coli bacteriophage r17 and f2 rnas , pseudomonas aeruginosa phage pp7 rna and newcastle disease virus rna ) are available , we are able to calculate the approximate number of nucleotides for these useful standards .
