Most lethal mutations in wild fruit flies are driven by newly transferred jumping genes, not small DNA errors, according to a new study from Duke University. The findings, published in PLOS Biology, ...

Geneticists have sought to understand the impact of genetic mutations, and what drives and maintains changes in DNA. Researchers have now reconstructed the evolution of a set of genes, and the ...

This produces point mutations in the DNA, which are mostly harmless but can sometimes lead to genetic disorders. In the new study, the Surrey researchers discovered that some of these modifications ...

Occasionally, single-letter misspellings in the genetic code, known as point mutations, occur. Point mutations that alter the resulting protein sequences are called nonsynonymous mutations, while ...

Although previously thought to be neutral, research in yeast suggests that synonymous point mutations may have strongly nonneutral effects. A group of researchers from the University of Michigan (MI, ...

A groundbreaking study published in this week’s issue of PNAS by scientists from Israel and Ghana shows that an evolutionarily significant mutation in the human APOL1 gene arises not randomly but more ...
