Expert
Primary constriction is the narrower area of a condensed chromosome where the centromere, the structure which unites similar chromatids, is situated. Secondary constriction is an area similar to the primary constriction, much narrower than the normal thickness of the chromosome too, and in common it is associated to genes which coordinate the development of the nucleolus and control the ribosomic RNA (or rRNA) synthesis. For this cause the secondary contrictions (which can be one or more in chromosome) is termed as nucleolus organizer region (or NOR).
