- Chromosome - Wikipedia
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

Having two copies of each chromosome ensures that you get the right amount of proteins made by the genes on those chromosomes This system can also protect you from some diseases
- 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)
- Chromosome | Structure Function | Britannica
chromosome, the microscopic threadlike part of the cell that carries hereditary information in the form of genes A defining feature of any chromosome is its compactness
- What is a Chromosome? Structure, Function, and Role in Genetics
A single human chromosome can carry hundreds or even thousands of genes, which are the instructions for making proteins—molecules that perform virtually all tasks in a cell, from catalyzing reactions to providing structure Each gene occupies a specific location, or locus, on a chromosome
- Chromosomes 101: The Key to Understanding Your Genome
Why Chromosomes are more than just DNA A chromosome refers to the thread-like structure, which is found in the nucleus of cells, including animals and plants Chromosomes are composed of DNA and proteins Histones coil DNA very tightly to form chromosomes; without the tight wrapping, DNA would be too long to fit in the cells Chromosomes play important roles within organisms, including in cell
- Chromosome: What It Is, Its Structure, and Function
Each eukaryotic chromosome is a complex structure made up of DNA tightly coiled around specialized proteins called histones This packaging is necessary because if all the DNA from a single human cell were unraveled, it would stretch approximately 6 feet
- Chromosome: MedlinePlus Medical Encyclopedia
Chromosome Chromosomes are structures found in the center (nucleus) of cells that carry long pieces of deoxyribonucleic acid (DNA) DNA is the material that holds genes It is the building block of the human body Chromosomes also contain proteins that help DNA exist in the proper form
