Solomon Spiegelman

Died 21 Jan 1983 at age 68 (born 14 Dec 1914).American microbiologist and geneticist who discovered that only one of two strands of molecules that make up DNA, carried the genetic information to produce new substances. The carrier was called ribonucleic acid (RNA). In 1962, he developed a technique that allowed the detection of specific RNA and DNA molecules in cells. This technique, called nucleic acid hybridization, is credited for helping to lay the groundwork for current advances in recombinant DNA technology. Much earlier, his Ph.D. thesis (1944) was the first work to establish that genes are activated and deactivated by compounds that he called inducers, which thus radically affect the pattern of proteins that a cell fabricates without actually altering the genes themselves.
