The 23S (1.1×106 mol.wt.) rRNA of Anacystis nidulans undergoes postmaturational cleavage to produce 0.9×106 and 0.2×106 molecular species. We have provided evidence in double labelling experiments, in which we could distinguish between the fate of molecules synthesized before and after infection, respectively, that infection with cyanophage AS-1 abruptly and completely inhibits the cleavage of 23S rRNA in Anacystis cells.
