DNA lends scientists a hand, revealing new chemical reactions
...own as "DNA-templated synthesis," that uses DNA to code not for RNA or proteins but instead for synthetic molecules. The researchers, led by Harvard University chemist David R.

The idea is that a short stretch of genetic code from a reference gene is sufficiently characteristic of one species to distinguish it from every other species, and that comparisons of sequence variations in that gene can also reveal evolutionary relationships among species.

...f glanders, scientists have deciphered the genetic code of the ancient pathogen that causes the horse disease: Burkholderia mallei.

"We've learned that the human genetic code only has a fraction of the genes we expected, and as a result it's become clear that the context of protein-to-protein interactions significantly affects what proteins can do," he explains.
