American #cellular #geneticist whose research (1950's - 60's) altered the prevailing view about where genetic material was within the #cell. In particular, she recognized that a second set of genes were found outside of the cell's #nucleus. Even though they were #nonchrosomomal, these genes also influenced inherited characteristics. Previously, only the #chromosomal #genes had been considered to control genetic behaviour.
Her research in later life turned to the study of genetic mechanisms involved in #cancer. She was among the first to study the role of #mutations in suppressor genes that neutralized their restraint on cell #reproduction
