Report Abuse. Chromosomes are made up of DNA packaged with histones and other proteins. DNA is deoxyribonucleic acid, an extremely long polymer whose repeating units are each made up of a phosphate plus a deoxyribose sugar plus a nitrogenous base.
Chromosomes, DNA and genes. The nucleus of a cell contains chromosomes that carry genetic information. Most body cells have the same number of chromosomes, but this varies between species. Human body cells, for example, each have 23 matching pairs of chromosomes. Chromosomes are made from long, coiled molecules of DNA. A gene is a shorter region of DNA that carries the genetic code for a particular characteristic or cell activity. DNA molecules contain chemicals called bases. Note that these are not the bases you come across in chemistry - which neutralise acids.
