Answer:
Chromatin
Explanation:
The unwound, filamented mass of DNA and associated proteins in a cell that is not dividing id termed as 'chromatin'. The major function of the chromatin is to pack the DNA into the compacted dense shape so that any type of tangling is avoided in the DNA strands. The chromatin is known to be present in every eukaryotic cell. It is due to chromatin that the chromosomes are properly segregated during the anaphase. The nucleus is the site where chromatin is present.
