AN IN VITRO-IDENTIFIED HIGH-AFFINITY NUCLEOSOME-POSITIONING SIGNAL IS CAPABLE OF TRANSIENTLY POSITIONING A NUCLEOSOME IN VIVO

An in vitro-identified high-affinity nucleosome-positioning signal is capable of transiently positioning a nucleosome in vivo

Abstract Background The physiological function of eukaryotic DNA occurs in the context of nucleosomal arrays that can expose or obscure defined segments of the genome.Certain DNA sequences are capable of strongly positioning a nucleosome in vitro, suggesting the possibility that favorable intrinsic signals might reproducibly structure chromatin seg
