...analysis, using a technique whose inventors won the 1993 Nobel Prize, is a sort of molecular copying process that zeros in on and amplifies a particular region of DNA. The differences at that site can then be distinguished through specialized probes that tiger a color change or through gel electrophoresis followed by a silver stain...
Lewontin and Hartl have fueled controversy over the statistics, not the techniques, of DNA profiling. "The foundation of the molecular biology is well laid," says James F. Crow, professor emeritus of genetics at the University of Wisconsin. "The difficulties are matters of the interpretation" of the profiles...
...Sciences after funding dried up for his research into how the billions of cells that make up the body communicate with one another. Working independently, Rodbell and Dr. Alfred G. Gilman of the University of Texas Southwestern Medical Center in Dallas discovered that the cells employ a kind of molecular switchboard to sort out incoming chemical and hormonal messages. The switches in this biological telephone system, molecules called G proteins, have since been implicated in everything from diabetes to alcoholism to whooping cough...
