Chromatin structure, diagram
Chromatin structure, diagram. The main artwork shows various molecules and a strand of DNA (deoxyribonucleic acid, red) looping round a cylindrical histone core (blue), forming a structure known as a nucleosome. The yellow region is a section of cytosine-guanine (labelled CpG-GpC) di-nucleotides that play a role in chromatin formation. Also shown here is acetylation, deacetylation, methylation, and demethylation. Strings of nucleosomes (lower left) form the structure called beads on a string. Further compacting (lower right) condenses the chromatin even more to fit inside cell nuclei

EDITORS COMMENTS
This print showcases the intricate structure of chromatin, offering a glimpse into the fascinating world of molecular biology. The main artwork depicts a strand of DNA elegantly looping around a cylindrical histone core, forming what is known as a nucleosome. The vibrant red color represents deoxyribonucleic acid (DNA), which plays a crucial role in genetic information storage. Highlighted within the image is a yellow region consisting of cytosine-guanine di-nucleotides labeled CpG-GpC. These specific molecules contribute to the formation of chromatin and its structural organization. Additionally, various processes such as acetylation, deacetylation, methylation, and demethylation are visually represented here. The lower left portion reveals strings of nucleosomes arranged like beads on a string – an arrangement referred to as "beads on a string". As we move towards the lower right corner, we witness further compaction and condensation of chromatin to fit inside cell nuclei. Through this artful representation created by Science Photo Library, viewers gain insight into the complex nature of chromatin and its vital role in genetic regulation. This diagram serves as both an educational tool for those studying biochemistry or genetics and an aesthetic marvel that captures the beauty found within our cells' molecular machinery.
