Polyadenylated RNA was detected in the cyanobacteria Nostoc sp. strain MAC and Anabaena variabilis by oligodeoxythymidylic acid-cellulose chromatography and by hybridization to [3H]polyuridylic acid. Polyadenylate tracts from A. variabilis were located at the 3' end of RNA chains and had an estimated length of 15 to 22 nucleotides.
