RNA Tie Club

The RNA Tie Club is a scientific "gentleman's club" of select individuals who contributed to the understanding of DNA and the manner in which it relates to proteins and/or the ability to "read" the "message" in DNA.[1]

Founding

Founded in 1954 by American biologist James D. Watson and Russian–American physicist George Gamow to "solve the riddle of the RNA structure and to understand how it built proteins" and with the motto "do or die; or don't try",[2] the club consisted of 20 members, each of whom corresponded to an amino acid, and an additional four honorary members (S. Brenner, VAL. F. Lipmann, A. Szent-Gyorgyi, and another individual), one for each nucleotide.[2]

Each member received a woolen necktie with an embroidered helix on them, hence the name "RNA Tie Club".[2]

The Tie and tiepin

Members of the RNA Tie Club were to receive a black wool-knit tie with a green and yellow RNA helix emblazoned on it. The original design of the tie came from Orgel, with the final pattern being a re-imagining by Gamow.[3][4] Gamow's tie pattern was delivered to a Los Angeles haberdasher on Colorado Avenue by Watson, with the shop tailor promising to make the ties for $4 each.[4] Along with each tie, members of the club were to receive a golden tiepin with the three letter abbreviation of their club amino acid designation. Not all members may have received their pin. Gamow, however, wore his pin on several occasions, often causing some confusion and questioning of why he was wearing the "wrong initials".[4]

Successes

Meetings of the RNA Tie Club were friendly, cordial affairs involving cigars and alcohol. This time allowed for bonding and close friendships among this scientific elite, and it turned out to be a breeding ground for creative ideas. While meetings were held twice a year, between meetings the members mailed letters and preprints of articles suggesting new concepts and ideas.[5]

Number of nucleotides in a codon

Using mathematics, Gamow postulated that a nucleotide code consisting of three letters would be enough to define all 20 amino acids. This concept is the basis of "codons", and set an upper and lower limit on the size of a codon.

Codons

Sydney Brenner proposed the concept of a codon, the idea that three nucleotides could code for one amino acid.[6] His proof involved statistics and experimental evidence from amino acid protein sequences.

Adaptor hypothesis

Francis Crick proposed the "adaptor hypothesis" suggesting that some molecule ferried the amino acids around, and put them in the correct order corresponding to the nucleic acid sequence.[7] He also suggested that there were 20 separate adaptor molecules.[8][9] This was later to be found true by Robert Holley and the adaptor molecules were named transfer RNAs.

Personal successes

Many members of the RNA Tie Club achieved professional success, with several of them becoming Nobel laureates. However, the ultimate goal of understanding and deciphering the code link between nucleic acids and amino acids was achieved by Marshall Nirenberg, who was not a member of the RNA Tie Club.[10]
