The Nucleus and its Functional Domains

ID #1179

Is there another term for a "functional domain?" In the notes the spaces between chromosomes are labeled "interchromosomal domains," and I was wondering if this is the same as a functional domain, I don't think it is. Also, doesn't it have many important roles in addition to separating chromosomal territories?

A functional domain is a collection of molecules in a particular region for a specific purpose. There are a lot of things going on in the nucleus, but none of them are happening randomly throughout the nucleus. For example, ribosomal subunits are assembled in the nucleolus, so we call the nucleolus a functional domain.
