A chromosome is a package of DNA containing part or all of the genetic material of an organism In most chromosomes, the very long thin DNA fibers are coated with nucleosome-forming packaging proteins; in eukaryotic cells, the most important of these proteins are the histones
- Chromosomes Fact Sheet - National Human Genome Research Institute
Each chromosome is made of protein and a single molecule of deoxyribonucleic acid (DNA) Passed from parents to offspring, DNA contains the specific instructions that make each type of living creature unique The term chromosome comes from the Greek words for color (chroma) and body (soma)
