Chapitre 1 : Transmission, variation et expression de l’information génétique1ère Spé

2019-2020

Des cellules différentes …. mais une information génétique identique entre cellules.

1. Comment l’information génétique des cellules peut-elle se transmettre sans modification au cours des divisions cellulaires ?
