how do we know mitotic chromosomes are derived from chromatin

Solution

Chromosomes are the structures that are found in the nuclei of the eukaryotic cells which contain DNA along with proteins, and chromatin is the material of the chromosomes. In order to find that the mitotic chromosomes are derived from chromatin, the fibers containing the mitotic chromosome are loosened which reveals the interphase chromatin when observed under the electron microscope. The observation through the microscope indicates that the chromosomes are in extensively folded state and hence it can be said that the mitotic chromosomes are derived from chromatin.
