The Unsung Scientist Behind the Building Blocks of DNA | Marie M. Daly

Marie Maynard Daly made significant contributions to genetics and medicine. Her research on atherosclerosis linked cholesterol to heart disease. She was the first Black woman in the U.S. to earn a Ph.D. in chemistry. Daly's work on DNA identified key nucleic acids and disproved the tetranucleotide hypothesis. She also discovered the role of histones in gene expression, which is crucial for understanding how genetic information is translated into proteins. Her findings laid the groundwork for modern genetics and cell biology.
