Researchers report evidence of biparental inheritance of mitochondrial DNA. Mitochondria, the energy-producing organelles of cells, contain their own compact genomes that are separate from the nuclear ...

Mitochondria are often called the powerhouse of the cell, and these organelles are well-known for their energy-generating abilities. They are also special among organelles because they carry a tiny ...

Transferring the nuclear genome from one egg into the cytoplasm of a donor egg is a strategy to enable women carrying mutations in their mitochondrial DNA to have healthy babies. A new study uses ...

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 ...

New research provides insight about the bedrock scientific principle that mitochondrial DNA - the distinct genetic code embedded in the organelle that serves as the powerplant of every cell in the ...

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 ...

Mitochondria are often described as the cell’s power plants, but a wave of new research suggests their genetic material may ...

An evolutionary "loophole" might explain why males of many species live shorter lives than their female counterparts, a new study finds. The loophole lies in the mitochondria, the energy-generating ...

Almost every type of human cell is powered by mitochondria, bean-shaped organelles that use oxygen to synthesize usable energy.* These structures evolved billions of years ago from free-swimming ...
