                            A chromosome region that stains 
            poorly or not at all; thought to contain the normally functioning 
            genes. Region of eukaryotic chromosome that is diffuse during interphase. 
            Presumably the actively transcribing DNA of the chromosomes. (See 
            heterochromatin)  |
