H32-H42 tetramer accounts for the diameter of the octamer and H32-H42 tetramer alone can organize DNA in vitro into particles that display the properties of the core particle.

The H32.H42 tetramer bound to DNA recruits two copies of the H2A.H2B dimer to complete the assembly of the final nucleosome

DNA enters at 1 o’clock and exits at just short of 11 o’clock on one axis and they change time after 180 degree rotation

The H3.H4 tetramers and H2A.H2B dimers each interact with a particular region of the DNA within the nucleosome can be shown by clock analogy.
