Ribosomal precursors and ribonucleic acid synthesis in Escherichia coli.
Ribosomes and immature ribonucleoprotein particles were isolated from extracts of log-phase cells grown under various conditions. Quantitative measurements were made to determine the relative amounts of immature particles present in the extracts. The results indicate that the steady-state level of ribosomal precursors accounted for essentially a constant fraction of the total ribonucleic acid (...
متن کاملChloroplast replication and chloroplast DNA synthesis in spinach leaves
Cultured leaf disks from young spinach leaves have been used to study chloroplast DNA synthesis in relation to chloroplast growth and repli cation. Autoradiographs prepared from thin sections show th a t labelling throughout disks is uniform. We consider th a t cultured leaf disks serve as a model system for studies of cell expansion and chloroplast replication during the development of spinac...

متن کاملConformational 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...
