Recombination of human mitochondrial DNA.
Human mitochondrial DNA (mtDNA) is a 16.5-kb, circular genome essential for the maintenance of mitochondrial function and is present in multiple copies in most cell types. High sequence divergence and maternal inheritance make mtDNA useful in tracing human lineages. Whether recombination occurs between mitochondrial genomes is a longstanding question in mitochondrial biology, human evolution, a...

متن کاملAnimal mitochondrial DNA recombination revisited
Exchange of homologous sequences between mitochondrial DNA (mtDNA) molecules is thought to be absent in animals, primarily because of a failure to observe clear cases of recombinant haplotypes in natural populations. However, whether mtDNA recombination occurs is a different issue from whether it produces new haplotypes. A requirement for the latter is heteroplasmy – the presence of more than o...
متن کاملRecombination in human mitochondrial DNA?
The possibility of recombination in human mitochondrial DNA (mtDNA) has been hotly debated over the last few years. In this study, a general model of recombination in circular molecules is developed and applied to a recently published African sample (n = 21) of complete mtDNA sequences. It is shown that the power of correlation measures to detect recombination in circular molecules can be vanis...
متن کاملRetrotransposon polymorphisms affect genic recombination in maize.
Maize exhibits a high degree of intraspecific variation in genome structure, most of which is due to intergenic retrotransposon polymorphsisms among unrelated varieties. For example, a comparison of eight haplotypes of the bronze1 (bz1) locus, which contains numerous retrotransposons, showed that sequence similarity between any two haplotypes ranged from 25 to 84% (Wang and Dooner, 2006). In th...
