Eukaryotic cells have many specialized complexes and organelles that perform crucial functions. Mitochondria are well known organelles that are critical energy generators, often called the powerhouses ...

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 ...

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 ...

Genetic inheritance is a bit like a giant cocktail where nature has fun mixing the ingredients to create a unique result: you. But did you know that some traits are exclusively transmitted by your ...

Using sequencing techniques, researchers associated 51 mutations in mitochondrial DNA with amyotrophic lateral sclerosis (ALS), an incurable degenerative neurological disorder that leads to muscle ...

As we age, the genes in our cells accumulate more mutations. This is one of the contributory factors to age-related diseases and the aging process. However, in a new study published in Science ...

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 ...
