New form of DNA modification may carry inheritable information

[#item_title] Scientists at the University of Chicago, Harvard University and the Chinese Academy of Sciences have described the surprising discovery and function of a new DNA modification in insects, worms and algae. Common DNA modifications occur through methylation, a chemical process that can dramatically change gene expression, which regulates the eventual production of proteins that carry out the functions of...

How Water Shapes DNA

Water[1] molecules surround the genetic material DNA in a very specific way. Scientists at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) have discovered that, on the one hand, the texture of this hydration shell depends on the water content and, on the other hand, actually influences the structure of the genetic substance itself. These findings are not only important in understanding the biological...
