What did McClintock argue in 1961?
Wu shows that McClintock drew parallels between maize controlling elements and the bacterial operon, but Jacob and Monod recast her contribution as mere mobility.

What they did
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).
What they found
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.
The limits
What it doesn't show
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.
Key terms
- Controlling elements
- McClintock’s maize systems that regulated gene expression, not only moved.
- Operon
- Jacob and Monod’s bacterial regulator-operator-structural-gene control chain.
- Matilda effect
- Under-recognition of a woman scientist, here also intellectual and epistemological.
- Episome
- Mobile bacterial element Jacob likened to McClintock’s controllers, flattening her control claim.

Common questions
Jumping genes only?
That is the Nobel/Keller story; McClintock thought control mattered more.
Why 1961?
She tried to win recognition by paralleling maize systems with the operon.
Did prizes settle it?
1965 credited bacterial control to Jacob and Monod; 1983 locked McClintock to mobility.
