The “demotion” of plants and animals, combined with Woese’s simultaneously brash and reclusive nature caused most biologists to vehemently disagree with his proposal. Woese turned his attention to the genetic code while setting up his lab at General Electric's Knolls Laboratory in the fall of 1960. Interest among physicists and molecular biologists had begun to coalesce around deciphering the correspondence between the twenty amino acids and the four letter alphabet of nucleic acid bases in the decade following James D.
