Researchers have determined the structure of a key genetic mechanism at work in bacteria, including some that are deadly to humans, in an important step toward the design of a new class of antibiotics. Information stored in genes is translated or expressed into proteins, the workhorse molecules that make up the body’s structures and carry its messages. In the classical view of gene expression, instructions stored in deoxyribonucleic acid (DNA) chains are copied into messenger ribonucleic acids. (source: urmc.rochester.edu)
