Abstract:
RNA from chloroplasts isolated from Spirodela oligorrhiza included relatively rapidly-labeled fractions with apparent molecular weights of 2.7; 1.2; 0.7; and 0.5×106. With longer labeling, radioactivity appeared in the mature rRNAs (1.1 and 0.56×106 MW). Chloramphenicol inhibited the appearance of labeled mature rRNA, but increased the net labeling and caused the accumulation of the pulse-labeled RNAs, effects similar to those reported for bacteria. © 1975 Oxford University Press.
