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. Although the DNA helical diameter is only 2 nm, the entire DNA strand in a single cell will stretch roughly 2 meters when completely unwound.[1] The entire DNA strand must fit within the nucleus of a cell, so it must be very tightly packaged to fit. This is accomplished by wrapping the DNA around structural histone proteins, which act as scaffolding for the DNA to be coiled around. The entire ...
