Quizplus · Accepted Answer

When a eukaryotic cell is not undergoing mitosis, the DNA and its associated proteins appear as a visible network of dark fibers called chromatin. The chromatin is loosely packed and dispersed throughout the nucleus, and is not condensed into the visible chromosomes that are seen during mitosis. The other options are incorrect: the nuclear envelope is the membrane surrounding the nucleus, the nucleosome is a complex of DNA and histone proteins that makes up chromatin, the nucleolus is a substructure within the nucleus where ribosomes are synthesized, and the nucleoplasm is the fluid-filled space within the nucleus where the other structures are located.
