Early Life and EducationEdit
Research and Later LifeEdit
In 1952 Chase was a young laboratory assistant to American bacteriophage expert Alfred Hershey at Cold Spring Harbor Laboratory at the Carnegie Institution for Science. This was where the well-known Hershey-Chase experiment was performed. The experiment showed that it was DNA, and not protein, that was the genetic material through which traits were inherited.
A series of personal setbacks through the 1960s ended Chase's career in science. She spent decades suffering from a form of dementia that affected her short-term memory. She died of pneumonia on August 8, 2003, at the age of 75.
