MSH: Double-stranded DNA of MITOCHONDRIA. In eukaryotes, the mitochondrial GENOME is circular and codes for ribosomal RNAs, transfer RNAs, and about 10 proteins.,CSP: double-stranded DNA of mitochondria; its code differs both from that of nuclear DNA and present day prokaryotes; evolves more rapidly than nuclear DNA; in eukaryotes, the mitochondrial genome is circular and codes for ribosomal RNAs, transfer RNAs, and about 10 proteins.,NCI: Typically small, circular, intronless, and maternally inherited, mitochondrial DNA (mtDNA) is the multicopy deoxyribonucleic acid genome of mitochondria, intracellular organelles responsible for vital respiratory chain and oxidative phosphorylation reactions in higher eukaryotes. Replicated and transcribed by a separate enzymatic machinery from that of nuclear DNA, mtDNA encodes only a subset of mitochondrial functions. (NCI04)
