What is the function of ATP-dependent chromatin-remodeling complexes in eukaryotic cells?

Explore ATP-dependent chromatin-remodeling complexes: These are protein complexes that use the energy from ATP hydrolysis to change the position of nucleosomes on DNA. This repositioning can make certain regions of DNA more or less accessible, thereby influencing gene expression.

Differentiate between chromatin remodeling and histone modification: Chromatin remodeling involves repositioning nucleosomes, while histone modification involves chemical changes to histone proteins, such as acetylation, which can also affect chromatin structure and gene expression.
