Researchers at the University of Vienna, along with collaborators from France, Germany, Switzerland and the U.S., have achieved a breakthrough in understanding how genetic drivers influence the ...

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 ...

Olfactory receptor (OR) genes, representing the largest multigene family in mammalian genomes, have undergone extensive evolutionary modifications characterised by dynamic patterns of gene duplication ...

Carrying multiple copies of antibiotic-resistance genes could be key to resistance spread and evolution in bacteria, particularly those in humans and livestock. Researchers at Duke University (NC, USA ...

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 ...

When cells divide and chromosomes are replicated for the daughter cells in a select type of cell called the germline, which is happening constantly in living things, sometimes things don’t go ...

Phytochelatin synthases (PCSs) produce phytochelatins—tiny, cysteine-rich peptides that bind and neutralize toxic metal ions such as cadmium and arsenic. These molecules act as the plant’s natural ...
