Androgenetic species of clam utilizes rare gene capture

(PhysOrg.com) -- In a new study published in the Proceedings of the National Academy of Sciences, biologist David Hillis from the University of Texas shows how the freshwater Corbicula clam utilizes rare gene capture to avoid ...

Study maps hotspots of genetic rearrangement

Researchers have zoomed in on mouse chromosomes to map hotspots of genetic recombination — sites where DNA breaks and reforms to shuffle genes. The findings of the scientists at the National Institutes of Health and ...

Microorganisms in toxic groundwater fine-tuned to survive

(PhysOrg.com) -- Microorganisms can indeed live in extreme environments, but the ones that do are highly adapted to survive and little else, according to a collaboration that includes Department of Energy's Oak Ridge National ...

Understanding why BRCA2 is linked to cancer risk

A new study shows exactly how the gene BRCA2, linked to susceptibility to breast and ovarian cancer, functions to repair damaged DNA. By studying BRCA2 at the level of single molecules, researchers at the University of California, ...
