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.

WebIn the third level of packing, a variety of fibrous proteins is used to pack the chromatin. These fibrous proteins also ensure that each chromosome in a non-dividing cell occupies a particular area of the nucleus that does not overlap with that of any other chromosome (see the top image in Figure ). WebDNA packing reaches its most condensed state during metaphase in mitosis in preparation for chromosome separation. Chromatin packing is dynamic and undergoes reversible changes in response to changes in gene expression and the cell cycle. Credit: Rao, A., Ryan, K. Fletcher, S. Hawkins, A. and Tag, A.
