Purpose It has been hypothesised that certain mitochondrial haplogroups, which are defined by the presence of a characteristic cluster of tightly linked mitochondrial DNA polymorphisms, would be ...

Mitochondrial DNA can be subdivided into various classes—termed haplogroups—on the basis of its pattern of single nucleotide polymorphisms. Several small, and as yet unreplicated, studies have ...

What happens to your cells when this DNA mutates? Similar to the nuclear genome, the mitochondrial genome is built of double-stranded DNA, and it encodes genes (Figure 2). However, the ...
