Microbes evolve predominantly by acquiring genes from other microbes, new research suggests, challenging previous theories that gene duplication is the primary driver of protein evolution in ...

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

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 ...

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 ...

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 ...

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 ...
