In most eukaryotes, the inheritance of mitochondrion and its DNA (mtDNA) is strictly maternal, despite the fact that a spermatozoon can inject up to 100 functional mitochondria into the oocyte during ...

The 100 or so organelles in sperm are swamped by hundreds of thousands of mitochondria embedded in each egg cell — each carrying the 37 genes in mitochondrial DNA. The contribution of only maternal ...

Doubly uniparental inheritance (DUI) of mitochondrial DNA (mtDNA) represents a rare and intriguing deviation from the standard model of strictly maternal inheritance. In bivalves, DUI manifests as the ...

A new study from deCODE genetics uses pedigrees and sequence data from 64,806 Icelanders to shed light on the rate and nature of mutations in mitochondrial DNA (mtDNA) and the peculiar dynamics of its ...

Earlier this week, a team of researchers announced that they’d made a discovery about how we inherit mitochondrial dna from ...

University of Nevada, Reno researchers Jeanne and David Zeh of the Department of Biology have received a five-year, $650,000 grant from the National Science Foundation to investigate the effects of ...

Recombination occurs in human mitochondrial DNA, says a team from the Beth Israel Deaconess Medical Center and Harvard Medical School, Boston, in a “proof of concept” paper in Science this week that ...

The human genome is contained in the nucleus of almost every cell in the body. But those cells also contain multitudes of mitochondria, and these incredible little power-generating organelles carry ...

Mitochondrial donation through pronuclear transfer resulted in several live births and reduced transmission of pathogenic mitochondrial DNA (mtDNA) variants, researchers reported. The study involved ...

In September 6 Nature, Sofia Berlin and Hans Ellegren from Uppsala University, Sweden, examine the controversial clonal inheritance theory for vertebrate mitochondrial DNA (mtDNA) by following ...
