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 ...

One study reported 8 live births from 22 women with pathogenic mtDNA variants who underwent mitochondrial donation through pronuclear transfer. None had signs of mitochondrial disease and heteroplasmy ...

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 ...

A high-throughput single-cell single-mitochondrial genome sequencing technology known as iMiGseq has provided new insights into mutations of mitochondrial DNA (mtDNA) and offers a platform for ...

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 ...

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 ...

When a four-year-old boy was brought to the Cincinnati Children’s Hospital Medical Center with fatigue, muscle pain and muscle weakness, doctors suspected there might be something wrong with his ...

Mitochondrial genomes are not uniform across cells of the body as previously believed, but vary between different tissue types, according to a study published online today (March 3) in Nature. Image: ...

You are a forensic scientist recruited to help solve a long-standing "missing persons" case. Mitochondrial DNA, or mtDNA for short, is the key to your success. Take careful notes as your teacher ...

Mitochondria, the cell’s powerhouse, exist at the center of cellular biosynthetic pathways and play a major role in energy production, controlling cell death and oxidative stress. Defects in ...
