The Nature and Processing of Ribosomal Ribonucleic Acid in a Dinoflagellate
Certain features of the dinoflagellate nucleus suggest that it represents a primitive form of eukaryotic nucleus. For this reason, it was of interest to characterize dinoflagellate ribosomal RNA (rRNA) and its mode of synthesis to determine if it also deviated from typical eukaryotic patterns. Gyrodinium cohnii was chosen for this examination. Gyrodinium ribosomal RNA species are 16 and 25s as ...
متن کاملRelationship between sporulation-specific 20S ribonucleic acid and ribosomal ribonucleic acid processing in Saccharomyces cerevisiae.
The nature and properties of the 20S ribonucleic acid which accumulates only during the sporulation of Saccharomyces cerevisiae were examined. The 20S ribonucleic acid (RNA) has a base composition considerably different from ribosomal RNA species and is virtually unmethylated. The 20S RNA did, however, exhibit approximately 70% homology with 18S RNA by RNA-deoxyribonucleic acid filter hybridiza...

15 صفحه اولConformational Changes in Ribosomal Ribonucleic Acid
Both rat liver and Escherichia coli rRNA in 0.1M-sodium chloride were titrated with acid or alkali over the range pH 3-7 at approx. 0°C. rRNA did not bind acid reversibly and hysteresis was observed, i.e. the plot of acid bound to rRNA against pH had the form of a loop showing that the amount of acid bound at a particular pH depended on the direction of the titration. Although the boundary curv...
