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 ...

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 ...

People interested in their genetic composition can learn about their DNA structure. The DNA molecule is a fundamental substance throughout human bodies, plants, plant organisms, and all microorganisms ...

Many interesting features distinguish human mitochondrial DNA from its nuclear counterpart, including the following: In the aforementioned study, Song and colleagues (2005) measured the ...
