Nucleosome molecule F006 / 9235

Nucleosome, molecular model. A nucleosome is a subunit of chromatin, the substance that forms chromosomes. It consists of a short length of DNA (deoxyribonucleic acid, red and blue helix) wrapped around a core of eight histone proteins (centre). Here the secondary structure of the proteins is shown. The structure of the nucleosome allows large quantities of DNA, the genetic material, to be packaged into a cells nucleus

EDITORS COMMENTS
This print showcases the intricate structure of a nucleosome molecule, F006 / 9235. A nucleosome is a vital subunit of chromatin, which forms chromosomes within cells. The image beautifully illustrates the complexity and elegance of this molecular model. In the picture, we see a short length of DNA, represented by the striking red and blue helix, elegantly wrapped around a core composed of eight histone proteins at its center. The secondary structure of these proteins is highlighted here, showcasing their alpha helices and beta sheets. The significance of this structure lies in its ability to efficiently package large quantities of DNA – our genetic material – into the nucleus of cells. This packaging mechanism plays an essential role in maintaining genome stability and regulating gene expression. The white background accentuates the detailed reflection and shadow cast by this molecular artwork. It serves as a reminder that biology research and medicine are intricately linked with understanding complex structures like these. This mesmerizing illustration not only represents scientific progress but also symbolizes advancements in healthcare through proteomics, genetics, biochemistry, and more. Created by LAGUNA DESIGN/SCIENCE PHOTO LIBRARY for non-commercial use only; it stands as a testament to human curiosity about life's fundamental building blocks - molecules like DNA - that shape our existence on both macroscopic and microscopic levels.
