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 genoma d'homínids té uns tres mil milions de parells de base, però el genoma d'un elefant o d'un mamut en té dos mil milions més, la majoria del qual es compon d'ADN petits i repetitius que dificulten realment retocar l'estructura del genoma.
