Hereditary non-syndromic deafness has been associated with a point mutation in the mitochondrial 12S rRNA gene. We present data from deaf individuals in 12 nuclear families originating from a small ...

Scientists have argued whether or not the often-studied mitochondrial DNA molecule is clonally inherited. It is with assuming clonal inheritance this type of DNA has been used to track the origin of ...

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 ...

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 ...

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 ...

Typically, humans inherit mitochondria and mitochondrial DNA from their mothers only. But using sequencing data from the mitochondrial genomes of members from three unrelated families, researchers ...

New research on tube anemones is challenging everything that evolutionary biologists thought they knew about sea animal genetics. The mitochondrial DNA of the tube anemone, or Ceriantharia, is a real ...

We all know: The mitochondria is the powerhouse of the cell. But the mitochondria is much more than a simple power plant. It’s also a unique source of DNA that can give us important clues to our ...

Because mtDNA is only passed down along maternal lines and mutates at predictable rates, it has been used to help trace migration routes of early humans. In this activity, students will learn how ...
