Mitochondrial DNA transmission genetics in crickets.
This paper presents the results of a single generation study of the transmission genetics of mitochondrial DNA in the field cricket Gryllus firmus. In this species, individuals heteroplasmic for at least two different-sized mitochondrial genomes can be collected easily from natural populations. The frequencies of mtDNA size variants in heteroplasmic females and samples of their offspring were e...
متن کاملMitochondrial DNA Mutations, Pathogenicity and Inheritance
Mitochondria contain their own DNA (mtDNA), which codes for 13 proteins (all subunits of the respiratory chain complexes), 22 tRNAs and 2 rRNAs. Several mtDNA point mutations as well as deletions have been shown to be causative in well-defined mitochondrial disorders. A mixture of mutated and wild type mtDNA (heteroplasmy) is found in most of these disorders. Inheritance of mtDNA is maternal, a...
متن کاملMitochondrial protein import.
Most mitochondrial proteins are synthesized as precursor proteins on cytosolic polysomes and are subsequently imported into mitochondria. Many precursors carry amino-terminal presequences which contain information for their targeting to mitochondria. In several cases, targeting and sorting information is also contained in non-amino-terminal portions of the precursor protein. Nucleoside triphosp...
