Explanation:
NORs (Nucleolus organizer regions) are chromosome regions in which ribosomal genes are encoded, while nucleoli (singular = nucleolus) are nuclear territories where ribosomes are produced and assembled. A nucleolus may contain one or more NORs.
Nucleoli are composed of DNA, RNA and proteins arranged around NORs.
The transference RNA (tRNA) genes are known to be spatially associated with the nucleolus as happen, for example, in <em>Saccharomyces cerevisiae</em>.
