Description
The image shows histone proteins (green). Histones add up to a self-assembly protein framework that enables the DNA to organize itself into a compact structure called chromatin. By dynamically changing its degrees of compaction and three-dimensional features, it accommodates its regulatory effects, roles, and functions. Histone proteins assemble DNA into sub-structural units called nucleosomes. They can be distinguished into four core histones. H2A, H2B, H3, and H4. The interaction between them and DNA is mediated by the amino-terminal (N-terminal) tail of the histone proteins.
