Chromatin exists in two structures. One structure, called euchromatin, is less solidified and can be interpreted. The resulting structure, called heterochromatin, is astoundingly thick and is usually not deciphered. Under the amplifying focal point in its sweeping structure, chromatin looks like spots on a string. The globules are called nucleosomes. Each nucleosome is made out of DNA collapsed more than eight proteins called histones. The nucleosomes are then wrapped into a 30 nm winding called a solenoid, where additional histone proteins reinforce the chromatin structure. During cell division, the structure of the chromatin and chromosomes are clear under a light amplifying instrument, and they change alive and well as the DNA is replicated and separated into two cells.
