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 ...

Genomes use the genetic code to write two separate languages. One describes how proteins are made, and the other instructs the cell on how genes are controlled.

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 ...
