Dysfunction resulting from mitochondrial DNA mutations has been implicated in multiple human pathologies, including ...

Explore the groundbreaking shift in the human mitochondrial DNA tree with ancestral genome insights for a more cohesive mtDNA reference. The new article in The American Journal of Human Genetics, A ...

Cells use a surprising “pearling” motion to evenly distribute mitochondrial DNA. This newly uncovered process may be key to ...

Mitochondrial diseases are a heterogeneous group of disorders with varying clinical features caused by impaired function of the mitochondrial respiratory chain. The underlying cause can be gene ...

The vast majority of our DNA—the chromosomes in the nucleus of each cell—is just what you’d expect: a mix of genetic material from both mother and father. But mitochondria are an exception. They ...

Mammalian mitochondrial DNA (mtDNA) is thought to be strictly maternally inherited. 1,2 Sperm mitochondria disappear in early embryogenesis by selective destruction, inactivation, or simple dilution ...

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

Provide each team with a copy of "The Hunt for mtDNA" student handout. Explain to students what mtDNA is, how it differs from nuclear DNA, and how it is inherited (see Activity Answer for more ...

When it comes to identification with DNA, forensic scientists have two basic approaches at their disposal. One approach analyzes nuclear DNA and is useful in identifying someone who is alive or has ...

Researchers identified a new, sticky form of mitochondrial DNA damage that builds up at dramatically higher levels than in nuclear DNA. These lesions disrupt energy production and activate ...
