Nirenberg's Genetic Code Chart, 1961-66 On May 27, 1961, Heinrich Matthaei, a postdoc working with NIH scientist Marshal Nirenberg, placed synthetic polyuracil RNA into 20 test tubes to see what it ...

But a first-of-its-kind comparison of genetic codes from 62 animals is beginning to tell the story of how people - and other mammals - lost their locks.

His experiment showed how RNA transmits encoded information in DNA and directs the building of proteins (the National Museum of American History owns a copy of his chart of 64 3-letter ...

Over the years, chemical biology methods have made an important contribution to the study of integral membrane proteins. A key modern approach is genetic code expansion (GCE), which makes it ...
