Talk:Nirenberg and Matthaei experiment

Citation for the poly U experiment
I changed the reference to the 1961 PNAS paper because I believe that is the first description of polyU driving the synthesis of polyPhe. The triplet nature of the code was not determined in this paper or in the 1962 paper. Nirenberg and his coworkers say that codons had to have a minimum of 3 bases in the 1962 paper. Similarly, Crick argues for multiples of 3. --JimHu (talk) 16:04, 21 January 2010 (UTC)
