The ABCs of New DNA: USD Professor Helps Expand Genetic Code

Wednesday, August 1, 2012

Inside USD -- The English alphabet has 26 letters, but until recently the genetic alphabet had four — adenine (A), guanine (G), cytosine (C) and thymine (T).

However, Tammy Dwyer, USD professor of chemistry and biochemistry, recently participated in research discovering that an expanded “DNA alphabet” could carry more genetic information than natural DNA, potentially enabling novel applications ranging from more precise molecular probes to nanomachines.

Dwyer contributed to The Scripps Research Institute’s study which was reported in the June 3 issue of the scientific journal Nature Chemical Biology. (Full Story)
