nucleolar 45s , 32s , and 28s rna 's had half-lives of 6.0 , 15.9 , and 26.5 min in normal rats , respectively , and 5.5 , 19.4 , and 22.9 min in protein-deficient rats , respectively considering the pool size of each nucleolar rna obtained from the leectrophoretic pattern , the turnover rates of 45s , 32s , and 28s rna 's were calculated to be the same , i.e. , o.189 pmoles/min/mg of nuclear dna , in normal rat liver and 0.372 , 0.372 , and 0.358 pmoles/min/mg of nuclear dna in protein-deficient rat liver , respectively .
