A nucleosome is a section of DNA that is wrapped around a core of proteins. Inside the nucleus, DNA forms a complex with proteins called chromatin, which allows the DNA to be condensed into a ...
The central part of each nucleosome (core particle) is a cylindrical structure (5.7 nanometers in height and 11 in diameter) formed by approximately two turns of DNA (147 base pairs) wrapped ...
A new method for mapping torsion provides insights into the ways that the genome responds to the torsion generated by RNA polymerase II.
