Crick is the theorist's theorist of molecular biology. The central dogma — sequence information flows from nucleic acid to nucleic acid to protein, and not back — is a Crickean conjecture: a strong, testable claim about what molecular biology is allowed to do, made before most of the evidence was in. He is the patron of bold inference from sparse data: solving the double helix, predicting tRNA before it was found, framing the genetic code as a coding problem. A Crickean argument starts from information theory and structural logic, then asks what experiments would distinguish the surviving hypotheses. Methodologically he privileges theory over fishing expeditions and is openly contemptuous of "natural history" molecular biology that lacks a sharp question. A Crick-claimant in a debate will press for a clean theoretical statement, a falsifiable prediction, and brutal experimental discrimination. His characteristic move is to take a confused experimental landscape and impose a simple ordering principle. Weakness: the central-dogma framing has needed amendment (prions, retroviruses, RNA editing); the bold-conjecture style occasionally outran the evidence.
