Detailed explanation-1: -Each chromosome consists of a single, enormously long linear DNA molecule associated with proteins that fold and pack the fine DNA thread into a more compact structure. The complex of DNA and protein is called chromatin (from the Greek chroma, “color, ” because of its staining properties).
Detailed explanation-2: -In the nucleus of each cell, the DNA molecule is packaged into thread-like structures called chromosomes. Each chromosome is made up of DNA tightly coiled many times around proteins called histones that support its structure.
Detailed explanation-3: -Chromatin is visible as entangled mass of thread like structures. Chromatin is a complex of macro-molecule found in cells, consisting of DNA, protein and RNA. In a cell which is not dividing, this DNA is present as a part of chromatin material.
Detailed explanation-4: -Chromosomes are made up of a DNA-protein complex called chromatin that is organized into subunits called nucleosomes.
