WebAll eukaryotes have a well-defined nucleus that contains DNA. DNA is a negatively charged polymer, packed compactly within the chromatin, engirdling the histone proteins, a ball of positively charged proteins. The octamer of histone proteins is wrapped with a DNA helix, giving rise to a structure called nucleosomes. WebHistones are proteins that condense and structure the DNA of eukaryotic cell nuclei into units called nucleosomes. Their main functions are to compact DNA and regulate chromatin, therefore impacting gene regulation. List the 4 core histones Histones H2A, H2B, H3 and H4 are known as the core histones, and they come together to form one nucleosome.
