WebChromosomes divide into 22 numbered pairs (autosomes) and one pair of sex chromosomes (X and Y). You receive one chromosome from each parent to make a pair. Although rare, errors occur when cells divide and replicate, so people might have an additional chromosome attached to a pair (trisomy) or one less chromosome on a pair … WebAs bundles of DNA that are tightly wound, chromosomes are found inside the nucleus of practically all of the cells in our body. Histone-like proteins, which give chromosomes their distinctive shape, keep DNA securely wound around them. Final answer: Chromosomes are made up of both DNA and proteins.
