Nucleosome core Model

This contains .blend file which you can modify as per your requirements. The .blend file also contains the timeline animation of camera zooming out to show the nucleosome. The structure is based on the PDB entry 1AOI (https://www.rcsb.org/structure/1AOI)

In eukaryotic cells, DNA is organized into a complex structure with the help of positively charged histone proteins. These proteins are rich in lysine and arginine, which carry positive charges in their side chains. Histones come together to form an octamer unit composed of eight molecules. The negatively charged DNA strand wraps around this histone octamer to form a nucleosome, which contains 200 base pairs of DNA helix. Nucleosomes are the basic repeating unit of chromatin, the thread-like bodies found in the nucleus. When viewed under an electron microscope, chromatin appears as a "beads-on-string" structure made up of nucleosomes. Overall, this complex organization helps to regulate access to genetic information and to condense DNA into a compact package.
