Every year, much of the energy the U.S. consumes is wasted through transmission, heat loss and inefficient technology -- costing American families and businesses money, and leading to increased carbon pollution.
histone /hisÂ·tone/ (hisÂ´tÅn) a simple protein, soluble in water and insoluble in dilute ammonia, found combined as salts with acidic substances, e.g., the protein combined with nucleic acid or the globin of hemoglobin. histone (hÄ­sâ²tÅnâ²)
Five major families of histones exist: H1/H5, H2A, H2B, H3, and H4. Histones H2A, H2B, H3 and H4 are known as the core histones, while histones H1 and H5 are known as the linker histones. The core histones all exist as dimers, which are similar in that they all possess the histone fold domain; three alpha helices linked by two loops.
