Nucleosome, 30-nm chromatin fiber, looped domain. the following lists represents the order of increasingly higher levels of organization of chromatin.

How are nucleosomes positioned in 30 nm condensed fibers?

A 30-nanometer chromatin fiber made of folded nucleosomes creates loops that are 300 nanometers in length on average. A 250 nm-wide fiber, which is snugly wound into a chromosome's chromatid, is created by compressing and folding 300 nm fibers.

A looping domain is what?

The loop domain is widely acknowledged to be the fundamental structural component of eukaryotic chromatin involved in DNA replication, gene expression, and higher order packaging.
