mitochondrial DNA

Sequencing of ancient samples showed that Denisovan Y chromosomes split around 700,000 years ago from a lineage shared by Neanderthals and modern humans.

Researchers characterized more than 100 ancient equid samples stretching over some 9,000 years, spanning the early Neolithic Age to the Iron Age.

Unlike previously described cytidine deaminases, this toxin catalyzes the deamination of cytidines within double-stranded DNA, the researchers said.

Sequences from 20 Neolithic and Iron Age individuals in sub-Saharan Africahelped retrace regional interactions between forager, pastoralist, and farming groups.

In Nature this week: hybridization and introgression affected genetic diversity of Dutch elm disease, genetic and phenotypic landscape of mitochondria in a Japanese population, and more.

Mitochondrial sequences suggest some haplogroups found in Finland today arrived in the region pre-Iron Age, though population distributions have shifted.

By combining mitochondrial DNA and climatic data, an international team of researchers found that an early mitochondrial lineage emerged in a paleo-wetland.

The PCR-based test analyzes mitochondrial DNA to detect prostate cancer in advance of biopsy, independent of prostate-specific antigen levels and age.
