Detailed explanation-1: -During this phase, the DNA is uncoiled and called chromatin. A pair of centrioles are present (but inactive in the cytoplasm) and the nucleolus is visible. At this time the cell grows, the DNA replicates and organelles grow in preparation for cell division.
Detailed explanation-2: -Chromosomes become visible, or in other words they condense. 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 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-4: -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.
