Chromatin beads, artwork
Chromatin beads. Computer artwork of strands of DNA (deoxyribonucleic acid, purple) coiled around histone cores (red) to form the less condensed form of chromatin. This less condensed form is known as the beads on a string form, as opposed to the more dense fibre form. DNA, the molecule that carries the genetic code that forms the basis of all life on Earth, is found in cell nuclei. It is a long molecule and has to be tightly coiled to fit inside the nucleus. Each set of two DNA loops around a histone core is known as a nucleosome. Further compacting and packaging (not seen here) form the denser forms of chromatin, and eventually the cells chromosomes

EDITORS COMMENTS
This artwork titled "Chromatin Beads" beautifully captures the intricate structure of DNA within a cell nucleus. The computer-generated image showcases strands of purple DNA elegantly coiled around red histone cores, forming the less condensed form of chromatin known as "beads on a string". DNA, the fundamental molecule carrying the genetic code for all life on Earth, is incredibly long and must be tightly compacted to fit inside the nucleus. Each set of two DNA strands looping around a histone core creates a nucleosome, which acts as a repeating unit in this packaging process. While this artwork only depicts the less dense form of chromatin, it hints at further stages where compaction and packaging occur to create denser forms and eventually chromosomes. The illustration highlights key concepts in biology, biochemistry, genetics, and cell biology by showcasing how proteins like histones play an essential role in condensing DNA into manageable structures within cells. It reminds us that even though these molecular processes are invisible to our eyes, they underpin every aspect of life's complexity. Science Photo Library has masterfully captured both scientific accuracy and artistic beauty with this print. It serves as a visual reminder of humanity's ongoing exploration into understanding our own genetic blueprint and unlocking nature's secrets at its most fundamental level.
