Duke Researchers Show "Editing" Can Fix Faulty Genes In New Approach To Gene Therapy
...e thana decade ago, that instead of being simply a passive carrier of geneticinformation, the genetic material known as RNA is an active participantin editing genetic messages before they are translated into protein. The editing approach to gene therapy ignores the defectivegenes, which are encoded in DNA a......obel prize-winning discovery that RNA is notjust a passive carrier of genetic code, but also can be an enzyme that activelyengages in chemical reactions.
