How do chromatin-remodeling complexes work?
A. They add methyl groups to the tails of histones in order to attract other proteins.
B. They use the energy from GTP hydrolysis to alter the arrangement of nucleosomes, rendering certain regions of the DNA more accessible to other proteins.
C. They use the energy from ATP hydrolysis to alter the arrangement of nucleosomes, rendering certain regions of the DNA more accessible to other proteins.
D. They remove acetyl groups from the tails of histones, rendering the DNA more accessible to other proteins.
E. They bind to nucleosomes in the 30-nm fiber and induce another level of packing, obscuring DNA from binding by other proteins.
Ans: C. They use the energy from ATP hydrolysis to alter the arrangement of nucleosomes, rendering certain regions of the DNA more accessible to other proteins.
