The precise functioning of the Lac operon would not be fully understood for some years. See Müller-Hill (1996) for a detailed insider’s account.

5.There is a large amount of material covering Nirenberg’s career in the Modern Manuscripts Collection, History of Medicine Division, National Library of Medicine at Bethesda. This includes over 40 volumes of diaries and notebooks – a future researcher’s goldmine. The diary covering this period is D9 IXA, 1960 Sep–[1961] May, to be found in Box 22, Folder 44, Marshall W. Nirenberg Papers, 1937–2003. The Nirenberg diary entries quoted here are all taken from Kay (2000). A tiny proportion of the papers can be found online at http://profiles.nlm.nih.gov/JJ/.

There was no prize for the co-discoverer of polynucleotide phosphorylase, the French biochemist Marianne Grunberg-Manago.

One of the controls later caused much confusion: to show that acidity was not involved in the DNase effect, they added several compounds, including polyadenylic acid, none of which affected protein synthesis. Polyadenylic acid is better known as poly(A); this ‘negative control’ later led some competitors to unfairly cast doubt on whether they had intended to get an effect with poly(U).

56.Stent (1971) described the experiment as follows: ‘One day, Nirenberg added artificially synthesised polyuridylic acid to this reaction mixture instead of natural mRNA and obtained a most surprising result’ (p. 528). See al
so Brenner (2001), p. 99.
57.Woese (1967), p. 53, note 1; Nirenberg (2004), p. 50. According to Woese, Beljanski’s results were ‘uninterpretable’. Nirenberg claims that Tissière had also tried and failed to get poly(A) to work, but Tissière said that although poly(A) was sitting in a freezer in the lab next door, he never thought to use it. He described his lack of initiative as ‘idiotic’ (Judson, 1996, p. 465).

10.When each batch of these synthetic RNAs was created, the nucleotides were assembled in a different, random way, producing slightly different molecular sequences, and making it difficult to compare studies that claimed to be looking at the same nucleotide ratios (Matthaei et al., 1962, p. 671).

Crick wrote to Ochoa apologising for criticising his work ‘in certain ways’ (Crick to Ochoa, 21 September 1962; http://profiles.nlm.nih.gov/ps/access/SCBBSY.pdf). A few months later Crick published a less combative version of these arguments in Science, but repeated his crushing statement that the experimental evidence for establishing a codon ‘falls short of proof in almost all cases’ (Crick, 1963b, p. 463).
