| Abstract: | We have determined the nucleotide sequence of a segment of Saccharomyces cerevisiae mtDNA that contains the structural genes for a cysteine-tRNA and a histidine-tRNA. The genes are approximately 85 bp apart, they do not contain intervening sequences or sequences coding for the 3'-CCA terminus and they are surrounded by nearly pure AT segments. The tRNAs deduced are very AT-rich, 74 and 75 nucleotides long, respectively, and contain one or more unusual features not found in tRNAs from other sources. |
