In turn, RNA molecules
serve as blueprints for the ordering of amino acids by
ribosomes during protein synthesis or translation. This simple
representation of the complex interactions and interrelationships
among DNA, RNA, and protein was proposed and
commonly accepted shortly after the discovery of the structure
of DNA. Nonetheless, this paradigm still holds more
than 45 years later and continues to represent a guiding principle
for molecular biologists involved in all areas of basic biological,
biomedical, and genetic research.
