Detailed explanation-1: -Consequently, during interphase, DNA is combined with proteins and organized into a precise, compact structure, a dense string-like fiber called chromatin, which condenses even further into chromosomes during cell division.

Detailed explanation-2: -During interphase the DNA strands are uncoiled (uncondensed) in the nucleus. This uncondensed genetic material is called chromatin; thus an uncondensed chromosome can be called chromatin.

Detailed explanation-3: -The complex of DNA and protein is called chromatin (from the Greek chroma, “color, ” because of its staining properties). In addition to the proteins involved in packaging the DNA, chromosomes are also associated with many proteins required for the processes of gene expression, DNA replication, and DNA repair.

Detailed explanation-4: -The DNA + histone = chromatin definition: The DNA double helix in the cell nucleus is packaged by special proteins termed histones. The formed protein/DNA complex is called chromatin. The basic structural unit of chromatin is the nucleosome.

Detailed explanation-5: -When a cell is in interphase, it is in a growth state maintaining normal metabolic functions. Because the DNA does not need to be separated (as it would in Mitosis) the DNA exists as chromatin.
