So actually, what happens inside the nucleus is we take our linear DNA and we wind it around special proteins known as histones. And then we basically take the histones, we connect those histones and we coil them further to create a structure known as the chromatin, which is a very, very condensed version of our linear DNA. So inside the nucleus, the linear DNA is wound around special structural proteins called histones, combining eight histones forms, a structure known as the nucleosome. And these nucleosomes can be wrapped into coils and super coils of complexes of protein DNA, RNA called chromatin. Now, when the DNA is not actually being used, when we are not transcribing our DNA molecule, it exists in this condensed super coiled form. However, to actually read and express, to actually transcribe our DNA molecule, we have to uncoil that section of the DNA.
