Ø Nucleosome units organized into more compact structure of 30 nm in diameter called 30 nm fibers (proposed by Rachel Horowitz & Christopher Woodcock in 1990).. Ø The H1 histone plays very important role in the formation of the 30-nm fiber. The protein-DNA structure of chromatin is stabilized by attachment to a non-histone protein scaffold called the nuclear matrix. Assistant professor Each cell has a pair of each kind of chromosome known as a homologous chromosome. Chromatin exists in two forms: heterochromatin (condensed) and euchromatin (extended). A nucleosome is a structure in your chromosomes, or bundled DNA. * Problem is packaging Levels of chromatin structure (nucleosomes, 30-nm fiber, loops, bands) Histone code marks active and inactive sequences DNA elements for chromosome structure include (ARS), TEL and CEN.
