Wu shows that McClintock drew parallels between maize controlling elements and the bacterial operon, but Jacob and Monod recast her contribution as mere mobility.

Key findings
Keller centred mobile elements; Comfort centred control. Wu argues control systems were the gender-neutral science that stayed under-recognised—the Matilda effect in intellectual form.
Methodology
Using 1961 papers, correspondence, and lecture manuscripts, the article contrasts Ac-Ds/Spm cytology with the regulator-operator-episome molecular story and the split Nobel memory (1965 vs 1983).
Limitations
This is a history of one conversation and its prizes, not a molecular re-analysis of transposition. It does not claim McClintock discovered the operon.

Role on claims
Each row is a claim on a concept or method page where this paper supports, challenges, or qualifies the statement. Roles are hand-checked — not a model guess.
McClintock drew parallels between maize controlling elements and the bacterial operon, but Jacob and Monod recast her contribution as mere mobility.
Evidence for the claim as stated.
Spemann’s anti-Drosophila stance is not a refusal of all heredity work; it is a different border from McClintock’s fight to be read as more than transposable-element mobility.
Evidence for the claim as stated.
Letters recover disagreements that later published or textbook accounts flattened. Darwin's letters to Huxley show Huxley refusing, before Origin, to let a theory of species change dictate classification, against the later story that evolution simply made classification genealogical. McClintock's 1961 correspondence and lecture manuscripts show her drawing parallels between maize controlling elements and the bacterial operon, a contribution Jacob and Monod recast as mere mobility.
Evidence for the claim as stated.
The same body of correspondence can support different readings. Wu notes that Keller centred McClintock's mobile elements while Comfort centred control, and argues from the 1961 papers and letters that control systems were the under-recognised contribution. The letters constrain but do not dictate the historian's emphasis.
