The correct order of chromatin organization from lower to higher levels is nucleosome, 30-nm chromatin fiber, and then looped domain. Nucleosomes are the basic unit of DNA packaging, consisting of DNA wrapped around histone proteins. These nucleosomes are further packed into the more compact 30-nm chromatin fiber, which in turn is organized into higher order structures such as looped domains.
