Chromosomes are tiny, threadlike structures inside most cells of every organism, or living thing. Chromosomes carry information about the organism in units called genes. When living things reproduce, they pass their genes along to their offspring.
Your body is made up of billions of cells, which are too small to see without a strong microscope. Inside most of those cells are chromosomes, which are thread-like strands that contain hundreds, or even thousands, of genes. Genes determine physical traits, such as the color of your eyes.
Learn what chromosomes are, how they look, and what they do in cells. Find out how humans and other animals have different numbers and types of chromosomes, and how genes and alleles determine traits.

Learn what chromosomes are, how they are made of DNA and genes, and how they vary in number and shape among different organisms. Find out how chromosomes help cells grow, reproduce, and build proteins.
A chromosome is a coiled structure of DNA found in the nucleus of cells made from many genes. A genome is one copy of an organism’s DNA.
