Gene duplication events in European eels have restored cell membrane permeability for urea and boric acid through mutated aquaporin genes. “The aromatic/arginine (ar/R) selectivity filter is a narrow ...

Noninvasive prenatal testing (NIPT), which relies on cell-free fetal DNA in the mother's blood, is increasingly common. Yet two studies published online Apri 1 in the New England Journal of Medicine ...

New research shows genome duplication in the ancestor of modern gymnosperms, a group of seed plants that includes cypresses and pines, might have directly contributed to the origin of the group over ...

Data from a new study links a pair of duplicated genes to human brain features. The research provides a roadmap for scientists to gain a deeper understanding of brain function and evolution, as well ...

Researchers at USC have developed a yeast model to study a gene mutation that disrupts the duplication of DNA, causing massive damage to a cell's chromosomes, while somehow allowing the cell to ...

A new study reveals how the duplication of the salivary amylase gene may not only have helped shape human adaptation to starchy foods, but may have occurred as far back as more than 800,000 years ago, ...

A team led by University of Pittsburgh School of Public Health geneticists has shown, for the first time, that a gene "silencer" that resides in junk DNA is directly sparing people from a devastating ...
