  1. The two H2A.H2B dimers each associate with 30 bp of DNA on either side of the central 60 bp of DNA bound by H3 and H4.

  2. Using the clock analogy again, the DNA associated with H2A.H2B is located from 5 o’clock to 9 o’clock on either face of the nucleosome disc.
  3. Together, the two H2A.H2B dimers form the upper part of the histone octamer located across the disc from the DNA ends
  4. Each nucleosome added to a covalently closed circular template changes the linking number of the associated DNA by approximately –1.2.
