Séquence enhancer
Une séquence enhancer est une région d'ADN qui peut fixer des protéines pour stimuler la transcription de gène. Le gène et la séquence enhancer ne sont pas forcément proches l'un de l'autre et peuvent même être sur deux chromosomes différents mais par contre le repliement de l'ADN dans le noyau leur permet une proximité physique.
