When a cell needs to duplicate, DNA strands are tightly coiled into chromosomes (chromosomes are made up of DNA and protein). Proteins form the structure of our bodies, as well playi… What is the relationship between DNA, genes, and chromosomes? Chromosomes are contained within the nucleus in eukaryotic cells, but can also be found in some of the other organelles such as mitochondria (where DNA is packed into a small circular chromosome). Mutation influence. A gene is one section of a chromosome, and a chromosome may carry many genes. Genes are relatively small sections of DNA which encode (provide a template for) proteins. Chromatin is the threads of DNA that get condensed to form chromosomes. The DNA double-strand which stores the cell’s genetic information should be packed into the eukaryotic nucleus for the existence.
