So a hominid genome is about three billion base pairs, but an elephant and mammoth genome is about two billion base pairs larger, and most of that is composed of small, repetitive DNAs that make it very difficult to actually re-jig the entire structure of the genome.
Un génome hominidé a environ 3 milliards de paires de bases, mais un génome d'éléphant ou de mammouth a environ 2 milliards de paires de base de plus et la plupart se compose de petits ADN répétitifs, ce qui rend très difficile de redistribuer l'ensemble de la structure du génome.
