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 ...

There are approximately 25 to 35 basic mitochondrial DNA haplogroups. To investigate the impact of mitochondrial DNA, Ballinger and his colleagues looked for changes in metabolism and nuclear gene ...

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 ...

Mitochondrial DNA haplogroups revealed substantial African matrilineal influence, with nearly one-third of Yemeni samples carrying African-specific mtDNA haplogroups such as L2a1, the most ...

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 ...

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 ...
