Nucleosomes are fundamental organizational units of chromatin which appear as “beads-on-a-string” arrangement. Here beads represent complexes of histones and DNA. Each bead contains a core of histone octamer: two copies each of , , , and ; out of 200 bp DNA, 146 bp DNA is bound tightly around the histone core and the remainder serve as linker DNA between nucleosomal beads. The histone associates with the linker DNA to pack adjacent nucleosomes together and forms a compact 30-nm chromatin fiber. Thus, the correct answer is A.
