Describe the four levels of chromatin structure, and explain how chromatin is decondensed to allow transcription.

The first level of DNA packaging is a nucleosome, which is comprised of histone proteins and DNA wrapped around the latter. The second level is a chromatosome, which is comprised of nucleosomes and H1 histones. The third level is a solenoid fiber, which is a helical structure of tightly packed nucleosomes. The fourth level is a scaffold of the solenoid fiber, which is created through loops in the fiber, which creates a chromatin structure. A chromatin structure is decondensed through condensing enzymes, which segregate the tightly packed regions by working on the protein complexes involved in DNA packaging.
