# bio (long form, separated for readability)
bio: |
  Jacques Lucien Monod was born in France on 9 February 1910 and trained as a biochemist. Working with François Jacob on E. coli and the lac operon, he built a model showing that a repressor protein binds to a specific DNA site — the operator — and blocks the manufacture of enzymes needed to break down lactose. The insight revealed the first clear system for how transcription gets regulated: genes aren't always on, they answer to molecular switches. Monod also proposed the existence of messenger RNA, the middleman carrying instructions from DNA to protein. He shared the 1965 Nobel Prize in Physiology or Medicine with Jacob and André Lwoff for discoveries on genetic control of enzyme and virus synthesis. He died on 31 May 1976, recognised as one of the founders of molecular biology.
