What is the role of H2 histone?: (A) Stabilize the 30-nm chromatin fiber, (B) Central role in the formation of the nucleosome, (C) Stabilizes the primary paicle, (D) Firmly binds two additional half-turns of DNA
Answer is D. Types Function H1 histones Stabilize the 30-nm chromatin fiber H2 histones H2A-H2B dimers stabilize the primary paicle and firmly bind two additional half-turns of DNA H3 histones H4 histones (H3-H4)2 tetramer has a central role in the formation of the nucleosome Reference: Harpers illustrated biochemistry 30th edition
