In the situation where Ki< K1, This form of mixed inhibition has been termed noncompetitive- uncompetitive inhibition

#Unit 2. Cellular Organization

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

Of the 147 bp of DNA included in the structure, the histone-fold regions of the H3.H4 tetramer interact with the central 60 bp.

#Id: 391

#Unit 2. Cellular Organization

The H3.H4 tetramer forms the top half of the histone octamer. Histone H3.H4 tetramers occupy a key position in the nucleosome by binding the middle and both ends of the DNA

#Id: 392

#Unit 2. Cellular Organization

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.

#Id: 393

#Unit 2. Cellular Organization

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.
