Nucleosome formation involves negatively charged DNA associating with positively charged amino acids on histone proteins, with histone N-terminal tails extruding and linking during supercoiling.
ADN nég. s'associe aux acides aminés pos. à la surface de la protéine histone, les queues N-terminales de l'histone sortent du nucléosome et se lient à d'autres lors de la superenroulement.
