− | Faced with the considerable challenge of packing more DNA into a cell, nature added proteins that reversibly compact the helix. The DNA can wind around these histone proteins, forming nucleosomes, that can then wind around each other to form chromatin. Other protein complexes modify and remodel the chromatin, making the DNA accessible for reading and copying. | + | Faced with the considerable challenge of packing more DNA into a cell, nature added proteins that reversibly compact the helix.
