The complex of proteins and dna in a nondividing cell is called

chromatin

Explanation:

Chromatin (from the Greek chromatos, color) is a collection of strands, each formed by a long DNA molecule associated with histone molecules, a special type of protein. These wires are the chromosomes.

The chromatin filaments intersect eucromatin points with heterochromatin points. These two varieties of chromatin proceed differently according to the time of cell life. In the interphase, the segments of heterochromatin appear to be spiraled (similar to a telephone cord), while the segments of eurochromatin are distended. Thus, the chromonemas appear thicker and more colored at the heterochromatin points and are so thin that they are almost imperceptible at the level of the eurochromatin points.
