Nucleus Chromosomes Diagram. Several levels of structural organisation are involved in the formation of chromosomes. Inside the nucleus are long coiled thread like structures that are sometimes invisible under an.
Chromosomes are normally visible under a light microscope only when the cell is undergoing the metaphase of cell division. The nucleus of a cell has a spherical shape. Most eukaryotic chromosomes include packaging proteins called histones which aided by chaperone proteins bind to and condense the dna molecule to maintain its integrity.
The following diagram below is the human chromosome diagram.

Contained within the nucleus is a dense membrane less structure composed of rna and proteins called the nucleolus. The structure of a nucleus encompasses nuclear membrane nucleoplasm chromosomes and.
