WebFeb 28, 2015 · CHAPTER 13 DNA Packaging in Chromatin and Chromosomes. C hromosomal DNA molecules of eukaryotes are thousands of times longer than the diameter of the nucleus and must therefore be highly compacted throughout the cell cycle. This folding is accomplished by combining the DNA with structural proteins to make chromatin.
