| Modern Genetic Analysis Chapter 2. The Structure of Genes and Genomes The Nature of Eukaryotic Nuclear Chromosomes Figure 2-22. Model for chromosome structure. On the left is shown a more relaxed supercoil, when the cell is not dividing. On the right, much tighter coiling is shown, representing a chromosome during cell division: here the loops are so densely packed, only their tips are visible. At the free ends the solenoids are shown uncoiled to give an approximation of relative scale.
