Detailed explanation-1: -(KROH-muh-some) A structure found inside the nucleus of a cell. A chromosome is made up of proteins and DNA organized into genes. Each cell normally contains 23 pairs of chromosomes.
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: -Chromosomes are made up of a DNA-protein complex called chromatin that is organized into subunits called nucleosomes.
Detailed explanation-4: -Chromatin Domains: the Unit of Chromosome Organization-PMC.
Detailed explanation-5: -Condensing DNA into chromosomes prevents DNA tangling and damage during cell division.
