Histone proteins form the support structure for the DNA in a chromosome. They help package and organize the long DNA strand into a more compact structure, which is necessary for proper cell division and gene expression.
The DNA of a chromosome carries information about the structure of genes, which are sequences that code for proteins and determine various traits and functions in an organism. Additionally, it contains regulatory elements that control gene expression, and structural features that help organize the chromosome within the cell nucleus. Overall, the DNA sequence provides the blueprint for the development, functioning, and reproduction of living organisms.

Down's Syndrome is an example of a birth defect characterized by an abnormality of the chromosome structure.
A single molecule of DNA consists of a double helix structure made up of nucleotides. Associated proteins, such as histones, help package and organize the DNA into chromatin. Together, the DNA and proteins form chromosomes within the nucleus of a cell.
DNA is packaged into a chromosome by wrapping around proteins called histones, forming a structure known as chromatin. This chromatin then coils and condenses to create the compact structure of a chromosome.
