Nucleotide Sequence Homology Exists between the Chloroplast and Nuclear Ribosomal DNAs of Euglena gracilis1

Abstract

The nuclear and chloroplast ribosomal DNAs from Euglena were shown to have specific regions of nucleotide sequence homology. The regions of homology were identified by hybridization of restriction endonuclease DNA fragments of cloned chloroplast and nuclear ribosomal DNAs to one another. The regions of homology between these two ribosomal DNAs were in that part of the genes that code for the 3′ end of the small rRNAs (16S and 19S) and near or at the DNA sequences coding for the 5S RNAs. The nucleotide sequence homology between these regions was estimated to be approximately 94% by the melting point depression of a hybrid formed between the two ribosomal DNAs.
