Meselson-Stahl Experiment

The Meselson-Stahl experiment, conducted in 1958, revolutionized our understanding of DNA replication. Utilizing heavy isotopes of nitrogen, they traced the replication process in E. coli bacteria. Their findings provided strong evidence for the semi-conservative model of DNA replication, where each daughter DNA molecule consists of one parent strand and one newly synthesized strand. This groundbreaking experiment laid the foundation for modern molecular biology, shaping our comprehension of genetic inheritance, evolution, and disease mechanisms. Meselson and Stahl's work remains a cornerstone in genetics, influencing research across diverse fields and inspiring further exploration into the intricacies of molecular biology.
