Detailed explanation-1: -A single molecule of deoxyribonucleic acid and a protein make up each chromosome (DNA). As bundles of DNA that are tightly wound, chromosomes are found inside the nucleus of practically all of the cells in our body.

Detailed explanation-2: -A chromosome is made up of proteins and DNA organized into genes. Each cell normally contains 23 pairs of chromosomes.

Detailed explanation-3: -In the nucleus, DNA forms a complex with proteins. This complex is called chromatin and is formed when the DNA wraps around nuclear proteins and then wraps around itself multiple times to condense the DNA into a smaller volume.

Detailed explanation-4: -What are chromosomes? Chromosomes are structures that look like thread, which live in the nucleus (center) of cells. One molecule of DNA and one protein make up one chromosome. Chromosomes are different sizes, and proteins called histones allow them to pack up small enough to fit in a nucleus.

Detailed explanation-5: -Chromosomes are made up of DNA and proteins (i.e. histones). These are thread-like structures present in nucleus of the cell and contain genetic information that is transferred from parents to next generation.
