The ribosomal RNA genes on Neurospora crassa mitochondrial DNA are adjacent
Biochim Biophys Acta.

Abstract
Hybridization of separated 24 S and 17 S ribosomal RNA from Neurospora crassa mitochondrial ribosomes to restriction fragments of mitochondrial DNA leads to the conclusion that the large and small ribosomal RNA are adjacent on the restriction endonuclease cleavage map of the DNA. The distance between the two genes is estimated at 900 basepairs. This result is consistent with the existence of a ribosomal precursor RNA in N. crassa mitochondria and is in contrast to the situation in yeast, where the ribosomal genes are far apart on the mitochondrial DNA. The position of the ribosomal RNA genes on the cleavage map of N. crassa mtDNA provides a start for ordering the Hind III restriction fragments.
