In science:

The diploid human genome consists of about 2 m of double stranded DNA, which is wrapped around histone protein octamers, forming nucleosomes every 180 to 250 bp.
A Random Loop Model for Long Polymers
The first stages of compaction are well-known (see ref. for a review): The DNA double strand is wrapped around histone octamers in a 1-and3/4 left-handed superhelical turn forming the so-called nucleosomes, which are connected by stretches of linker DNA.
A Random Loop Model for Long Polymers
This decision would be determined by the presence in the embryo cells of certain chemicals in asymmetrical quantities and would then be “stored” in the nucleus through changes in the histone-arginine methylation patterns of specific DNA segments.
Epigenetic Tracking, a Method to Generate Arbitrary Shapes By Using Evolutionary-Developmental Techniques
However, CROGIDs do have one advantage over NCBI Gene IDs in that they are protein-based and hence identical protein products of several genes (like histones) are clustered together.

In the general model, there is usually a region that nucleates silencing by recruiting a silencing complex incorporating a histone modifying enzyme (figure 1).
