Joan Elaine Argetsinger Steitz (born January 26, 1941) is Sterling Professor of Molecular Biophysics and Biochemistry at Yale University and Investigator at the Howard Hughes Medical Institute. She is known for her discoveries involving RNA, including ground-breaking insights into how ribosomes interact with messenger RNA by complementary base pairing and that introns are spliced by small nuclear ribonucleic proteins (snRNPs), which occur in eukaryotes.
Steitz was born in Minneapolis, Minnesota. She grew up in Minnesota in the 1950s and 60s at a time when there were virtually no female role models in molecular biology. She attended the then all-girls Northrop College for high school.
In 1963, Steitz received her Bachelor of Science degree in chemistry from Antioch College, Ohio, where she first became interested in molecular biology at Alex Rich's Massachusetts Institute of Technology laboratory as an Antioch "coop" intern.
After completing her undergraduate degree, Steitz applied to medical school rather than graduate school since she knew of female medical doctors but not women scientists. She was accepted to Harvard Medical School, but having been excited by a summer working as a bench scientist in the laboratory of Joseph Gall at the University of Minnesota, she declined the invitation to Harvard Medical School and instead applied to Harvard's new program in biochemistry and molecular biology. There, she was the first female graduate student to join the laboratory of Nobel Laureate James Watson, with whom she first worked on bacteriophage RNA.
