Histone packaging of DNA. Illustration of the histone packaging of deoxyribonucleic acid (DNA). DNA has several associated packaging mechanisms, one of which is shown here. The DNA has been wound tightly into coils that wrap around proteins called histones (red). Further coiling (not shown) forms strands of chromatin which condenses during cell division to form structures called chromosomes. | |
