Summary Introduction

To review:

The different levels of packing of the linear DNA during the prophase.

Introduction:

The human DNA (deoxyribonucleic acid) is around 2 meters long if put end to end, but it fits inside a very small nucleus. This is achieved by extensive packing of the DNA. This packing is done with the help of positively charged proteins that are known as the histones. The histone proteins contain a high amount of arginine and lysine residues.
