When a double helix DNA strand is wrapped around proteins, this is called the beads on a string form of chromatin. These regions are then tightly packed to generate packed nucleosomes.
The nucleosomes are again packed tightly to form a chromosome scaffolds, which in turn form a part of chromosome.

3. Persistence length of DNA and energy cost of bending DNA around histone proteins (a) DNA is stiff because it is a double helix. At room temperature in dilute solution the persistence length of DNA is found to be p-50 nm. Using this persistence length, find the bending spring constant of DNA (b) In chromosomes, DNA molecules are wrapped tightly around histones. Consider wrapping a DNA molecule around a full circle, estimate the energy cost of bending DNA around the...

For the enhanceosome, binding sequences are on both strands of DNA. Why? The proteins of the enhanceosome on one strand have a regulatory function, whereas those on the other strand bend the DNA strand. The proteins on one side of the strand bind to GC rich regions and those on the other strand bind to AT rich regions. The proteins of the enhanceosome completely enclose the double helix and straightened the double helix. The proteins on one strand clear the...

Identify the most accurate term related to chromatin remodeling. DNA is associated with proteins to form. A is compsed of DNA wrapped around an octamer of histone proteins. An activator can increase transcription by attracting a to the region. Addition of (-COCH_3) groups to histone amino terminal tails results in a/an in gene expression. Removal of acetyl groups from histones results in a/an in gene expression.

Select the phrases that accurately describe properties of the most common form of the DNA double helix
Select the phrases that accurately describe properties of the most common form of the DNA double helix. There is more than one correct answer. Select all that apply. DNA contains equal amounts of adenine and thymine, and equal amounts of cytosine and guanine. A helical turn consists of about 10 nucleotides. Base pairs have a spacing of 20 A. The phosphodiester bonds between nucleotide residues run in opposite directions in the two strands. The nitrogenous bases are exposed to the solvent, whereas the sugar-phosphate backbone of...
