Abstract

The ribosomal RNAs were isolated from cyanobacteria ( CA and MAC) and labelled with [-P]ATP and polynucleotide kinase. DNA from the corresponding species was isolated, digested with RI or III, and resolved on agarose gels. hybridization was used to measure the number and location of the 16S and 23S ribosomal RNA genes. The comparative results are discussed in relation to the known genome size of these species and to their RNA content per cell.
