I love classic literature! Classic biochemistry papers that is! Not only are their findings fundamental, but the articles tend to be more detailed and easier to read (though not always!). So here’s a guide to some (but certainly not all) key early experiments and writings involved in figuring out how biochemical recipes are written!

  • Figuring out genetic information can be shared (& studied!) & “transform” one form of bacteria into another
    • Griffith, 1928 – the “transforming principle”

Griffith found there was a transforming principle, but what was it? 

  • Figuring out DNA is the transferer of genetic information
    • Avery, MacLeod, & McCarty, 1944
    • Hershey & Chase, 1952 (blender experiments)

DNA was the transforming principle, not protein! But DNA holds the instructions for making protein! 

  • Showing a direct, heritable link between DNA sequence and protein sequence
    • Pauling et al., 1949
    • Ingram, Ingram & Hunt, 1956 

and here’s how it’s read

  • Figuring out the genetic code is non-overlapping
    • Brenner, 1957; Tsugita & Fraenkel-Conrat, 1960; Wittman, 1966 
  • cracking the genetic code (what nucleic acid “words” (codons) “spell” (code for) which protein “letters”)
    • Nirenberg, Matthaei, 1961 – “polyU experiment”
    • Nirenberg and Leder, 1964 – “filter-binding experiments”
    • in addition to work by others including; Khorana; Grunberg-Manago, Oritz, & Ochoa
