Protein synthesis
... During the 1950s and 1960s, it became apparent that DNA is essential in the synthesis of proteins. Proteins are used in enzymes and as structural materials in cells. Many specialized proteins function in cellular activities. For example, in humans, the hormone insulin and the muscle cell filaments a ...
