Deciphering the Genetic Code: A 50 Year Anniversary

By Christie Moffatt Fifty years ago, on January 18, 1965, Dr. Marshall W. Nirenberg (1927–2010) completed his first summary of the genetic code—one of the most significant documents in the history of twentieth-century science—a painstaking, handwritten chart of the discovery of how sequences of DNA, known as “triplets,” direct the assembly of amino acids into […]

Preserving Nirenberg’s Genetic Code Chart

By Kristi Wright and Holly Herro The National Library of Medicine is home to a series of very important documents in scientific history—Marshall Nirenberg’s Genetic Code Charts. The charts contain original, handwritten data from experiments that determined how protein sequence was dictated by the sequence of precursor ribonucleic acids (RNAs). Conservators at NLM have been […]
