The RNA Tie Club was an informal group focused on deciphering the genetic code, where exclusive members exchanged ideas and each received a tie with a double helix, along with an assigned amino acidβ€”true or false? πŸ€”

See answer

 

βœ… True

πŸ‘” George Gamow (1904–1968), renowned physicist and contributor to the Big Bang Theory, founded the RNA Tie Club in 1954
πŸ”¬ It had 20 regular members (one for each amino acid) and four honorary members (one for each nucleotide base)
🧬 Members wore wool ties with a green and yellow double helix design

 

πŸ” George Gamow

🧩🧬 George Gamow was the first to attempt to decipher the genetic code
πŸ’ŽπŸ”‘ He proposed the diamond code, approaching the problem independently of biochemical constraints
🧬✨ His model allowed for 20 amino acids, leading to the concept of the “magic twenty”

 

πŸ‘” The RNA Tie Club

πŸ’‘πŸš« The club helped advance molecular biology through collaboration but did not achieve the goal of deciphering the genetic code
πŸŽ‰πŸ† In 1961, the non-members Marshall Nirenberg (1927–2010) and Johann Matthaei (*1929) demonstrated that:
Β Β Β Β Β Β Β Β  o messenger RNA is required for protein synthesis
Β Β Β Β Β Β Β Β  oΒ  synthetic messenger RNA preparations can be used to decipher various aspects of the genetic code

“They produced a long RNA chain consisting of a single nucleotide. When this resulted in a long chain of a single amino acid, the first part of the genetic code puzzle fell into place.”

πŸ‘‰ Fun Fact

πŸ˜„πŸŒŸ Gamow had a charming personality and quirky sense of humor
πŸ“„βœοΈ In the publication “The Origin of Chemical Elements”, written with his Ph.D. student Ralph Alpher, he wanted to make his completely uninvolved friend Hans Bethe (Nobel Prize for Physics in 1967) a co-author, only to have the list of authors read Alpher, Bethe, Gamow
πŸ”€πŸŒŒ This Ξ±-Ξ²-Ξ³ paper introduced the Big Bang Theory for the first time [1].
