Jean-François Joanny Matière molle et biophysique Collège de France Année 2023-2024 Séminaire - Ariel Amir : Correlations and Causation in the Bacterial Cell Cycle Ariel Amir Institut Weizmann Résumé How do cells control their size and couple the various ongoing cellular processes? Over the last decade, techniques were developed for extracting information pertinent to this question from correlations between key cell cycle variables, such as size and generation time. I will review this, as well as recent progress showing how conditional correlations (involving more than two variables) help prove the coupling between DNA replication and cell division in bacteria.
