Characterization of messenger RNA populations of Crithidia fasciculata

Cells of Crithidia fasciculata taken from exponentially growing cultures display a relatively high content of poly(A) RNA (roughly 45% of the total) in a nonpolysomal compartment. The proportion of this fraction is significantly higher than that of the free ribosomal units. This RNA is translational...

Summary:Cells of Crithidia fasciculata taken from exponentially growing cultures display a relatively high content of poly(A) RNA (roughly 45% of the total) in a nonpolysomal compartment. The proportion of this fraction is significantly higher than that of the free ribosomal units. This RNA is translationally competent and is indistinguishable from polysomal mRNA by various criteria. The significance of these findings is discussed with respect to the protein synthesis capability of the cell and the metabolic relationships between the cytoplasmic compartments of mRNA.
