| Modern Genetic Analysis Chapter 2. The Structure of Genes and Genomes The Nature of Eukaryotic Nuclear Chromosomes Figure 2-24. Three different diagrammatic ways of representing chromosomes in nondividing cells. The first representation focuses on the coiled structure of chromosomes. The second emphasizes the fact that the genetic component of a chromosome is DNA. The third shows the chromosomes as wormlike structures with centromeres as white circles. No representation is perfectly accurate, but each has its uses in genetics.
