Bivalves are an extraordinary class of animals in which species with a doubly uniparental inheritance (DUI) of mitochondrial DNA have been described. DUI is characterized as a mitochondrial homoplasmy ...

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 ...

Bivalve mollusks display one of the most intriguing exceptions to strict maternal inheritance of mitochondria in the animal kingdom. In many bivalves, a system known as doubly uniparental inheritance ...

Researchers at the Max Delbrück Center and the University of Oxford have found that a cellular housekeeping function called autophagy—by which cell components are broken down and recycled—plays a ...

In most plants and animals, including humans, mitochondria are inherited exclusively, or nearly exclusively, from the mother. By contrast, paternal transmission is observed only occasionally, and the ...

Back in the 19 th century, as the US grappled with the aftermath of the Civil War, Jesse James, leader of a notorious gang of outlaws, rose to prominence. He robbed banks and trains for over a decade ...

Researchers from Karolinska Institutet have discovered how mammalian cells prevent the gradual buildup of harmful mutations in mitochondrial DNA, the small but vital genome that powers every cell. The ...

Researchers have identified a physical process called “mitochondrial pearling” that explains how cells keep their mitochondrial DNA evenly spaced and ready for inheritance during division. The finding ...
