Charles Yanofsky

 

(born April 17, 1925, New York, N.Y., U.S.) U.S. geneticist. He received his Ph.D. from Yale University. He was part of the research team that first demonstrated that certain mutant genes produce inactive proteins. Later, working with E. coli, he showed that the sequence of the nitrogenous bases that form part of the structure of the genetic material corresponds to the amino acid sequence of proteins. Investigating the biochemical actions of suppressor mutations (changes in a gene that reverse the visible effects of mutation in a second gene), he found that suppression restored the ability to form an active enzyme in a mutant that had previously produced an inactive protein.

Charles Yanofsky (born April 17, 1925) is a leading American geneticist.

Born in New York, Yanofsky studied at the City College of New York and at Yale University.

In 1964, Yanofsky and colleagues established that gene sequences and protein sequences are colinear: changes in DNA sequence can produce changes in protein sequence at corresponding positions. His work has revealed how controlled alterations in RNA structure allow RNA to serve as a regulatory molecule in both bacterial and animal cells.

Yanofsky was co-recipient of the Louisa Gross Horwitz Prize from Columbia University in 1976 with Seymour Benzer.Yanofsky was elected a foreign member of the Royal Society in 1985 and was one of the recipients of the 2003 National Medal of Science awards.

Charles Yanofsky is now the Morris Herzstein Professor of Biology and Molecular Biology (Emeritus) at Stanford University.
