Figure 03-03: DNA in the interphase nucleus is organized and packaged. First, the DNA is wrapped around core histones to form nucleosomes. H1 then helps loop nucleosomes together into a fiber, which then can be further looped and packaged inside the nucleus in a highly organized manner.Chromatin is a packaging material for DNA. If not packed well, it can tangle around itself or get damaged during cell division. The size of cells is in micrometers and a DNA can be as long as 3 meters. In order to fit such a lengthy structure into a micrometer cell, tight packing is required. Chromosomes are made of tightly packed DNA molecules. We can compare this to the more diffuse chromatin, which refers to the less condensed, more dispersed form of DNA found during the interphase of the cell cycle. The former, on the other hand, is often seen during active cell division only. List the four phases of mitosis, and briefly explain what occurs during each phase.
