DNA research offers clues on cell mutation

A team of researchers from Colorado State University has been studying DNA damage in living cells to learn more about how genetic abnormalities arise. It has long been known that DNA molecules in every cell get constantly ...

Leaky genes put evolution on the fast track, researchers find

Small genetic mutations that add up over time could create an evolutionary express lane that leads to the rapid development of new traits, researchers from the University of Pittsburgh and the University of Wisconsin at Madison ...

Researchers clarify bacterial resistance

Just like plants and animals, bacteria have a range of defence mechanisms against viruses and other threats. Dutch researchers at the Wageningen Laboratory for Microbiology and their American and Russian colleagues have largely ...

Tracking a network of 100,000 mutants

What fundamentally sets a human being apart from every other living creature comes down to differences in DNA sequences—a set of genetically-inherited molecules found in every cell of every organism. These differences have ...

When the cell's two genomes collide

(Phys.org)—Plant and animal cells contain two genomes: one in the nucleus and one in the mitochondria. When mutations occur in each, they can become incompatible, leading to disease. To increase understanding of such ...

Modeling Genomic Erosion

(PhysOrg.com) -- Even though scientists have successfully sequenced the human genome, they still lack a clear picture of exactly how coding and non-coding DNA sequences function together, or how genomes evolve over time. ...
