Chromatin remodeling enzyme complexes _______________. Choose all that apply. A. ...are able to bind to the chromatin structure anywhere and cause DNA within a nucleosome to be repositioned. B. ...are non-histone proteins that can bind to the chromatin in interphase nucleus. C. ...bind to chromatin by binding to chemical modifications in the histone tails. D. ...cause DNA to be repositioned for access or tighter packing. E. ...are essential for regulating gene expression. F. ...promote the transition from the 30nm fibre to the 11nm fibre.

'Histone modifications lead to changes in chromatin structure Which of the following is not a possible outcome of those changes? They help recruit other proteins to the chromatin: They cause the histone N-terminal tails to bind less tightly to the core nucleosome. They directly lead to changes in the positions of the core histones. They cause the histone N-terminal tails to bind more tightly to the core nucleosome.'
