3 Billion Base Pairs per Cell


7 days

From The Biology of Prenatal Development.Buy Now

Script: Chaque cellule humaine contient environ 3 milliards de ces paires de bases.

L'ADN d'une seule cellule contient tant d'informations que, s'il était représenté en mots imprimés, la simple liste de la première lettre de chaque base exigerait plus de 1,5 millions de pages de texte!

Disposé en une seule ligne, l'ADN d'une seule cellule humaine mesure 1 mètre.

All ages referenced to fertilization, not last menstrual period.
