Using this clue as their Rosetta stone, Nirenberg and other researchers eventually found one or more three-letter code words, or codons, that could call up every single amino acid?plus other words that acted as punctuation, marking the start or completion of a message ordering the production of a protein. Even more remarkable, they learned that the code was universal: the same four letters, taken three at a time to form a single genetic word, code the same amino acids in all living things. Thus by the mid-1960s, scientists finally understood how DNA passes on genetic information with...
...many years, Señorita de la Jara immersed herself in Inca history and painstakingly catalogued tocapus. But she failed to find what she was looking for: an Inca equivalent of the Rosetta stone, the key that opened ancient Egyptian hieroglyphs to modern understanding. Finally, she turned her researches over to Barthel. With the same shrewdness that enabled him to decipher several Allied codes during World War II, Barthel made use of an important clue in her material. Many of the Inca vessels bore pictures as well as tocapus. In fact, one common scene portrayed the act of toasting...
...Saigon, Bureau Chief Marsh Clark, who coordinated the reports from Cambodia, Laos, Thailand and South Viet Nam, reported that telex communications even between such major centers as Bangkok and Saigon were "so bad that for a time they looked like a drunken man's version of the Rosetta stone." Bangkok Bureau Chief David Greenway, who filed exhaustively on the political implications of the coup, reported the same trouble from his end, as did Correspondent Robert Anson, working on the story in Vientiane, Laos. At one point Anson noted that he had managed to set up a private minibureau...

...Nirenberg, then an obscure young scientist at the National Institutes of Health, provided the biological Rosetta stone. After synthesizing a single helix with half-stairs that were the equivalent of only one of DNA's nucleotides-adenine (A)-he added it to a solution containing all 20 amino acids. Only one protein was produced in the solution. It consisted entirely of a chain of amino-acid molecules called phenylalanine. Thus, Nirenberg concluded, a three-letter code word made up of adenine nucleotides (AAA) was nature's instruction to the cell to use phenylalanine in building a protein...
