abstract：:The mRNAs from two yeast mitochondrial genes cob-box (cytochrome b) and oxi-3 (cytochrome oxidase 40,000 dalton subunit) are processed from large (7-10 kb) precursors. Certain mutations in each gene block the maturation of the RNAs from both genes at a variety of specific steps. The pleiotropic cytochrome b mutants se...
