A new study finds that mitochondria in our brain cells frequently fling their DNA into the cells' nucleus, where the mitochondrial DNA integrates into chromosomes, possibly causing harm. As direct ...

Gene editing technology allows to introduce and correct disease-linked mitochondrial DNA mutations in liver and skin cells In a step toward treating mitochondrial diseases, researchers in the ...

One of the world's greatest genetic mysteries is how a DNA marker present in Europe reached North America, leaving no clear trail through Siberia or Alaska. Scientists have been baffled by how ...

Researchers constructed a phylogenetic tree based upon human mitochondrial DNA (mtDNA) variation. A branch bifurcates whenever they found an additional polymorphism. At the top of the inverted tree is ...
