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.
The backbones of both substances consist of alternating molecules of phosphate and sugar. Nucleotide bases make up the rungs attached to the backbone. Of the two types of nucleic acids, DNA is more stable, making it less likely to be broken down than RNA. Your genes are made up of DNA, and each gene provides the code for making a specific protein.
