Similarities among ribosomal RNA's of angiospermae and gymnospermae

Journal of Molecular Evolution, 1976
Competitive hybridization of ribosomal RNAs was used to estimate similarities of nucleotide sequences between species of Angiospermae and Gymnospermae. Similarities have been measured with respect to Cucumis sativus. In Angiospermae the nucleotide sequences are highly conserved except in the species of the family of Compositae, where the percentages of
