Some rather amazing news out of Pittsburgh this week: Scientists at Carnegie Mellon recently announced a new therapy for inherited blood disorders in which synthetic “patch” molecules are inserted into malfunctioning DNA.
It works like this: peptide nucleic acid molecules, or PNA, are biomolecular structures created in the lab that can essentially mimic DNA. When injected into a living organism, they can repair specific breaks in DNA chains that are mapped to particular blood disorders
