The DNA-packaging function of histones allows long DNA molecules, in the form of chromatin, to fit neatly into the cell nucleus. Histones, through the formation of chromatin, also influence the accessibility of DNA to transcription machinery and therefore serve an essential role in controlling gene...
Cis Gene Regulation at the Single Cell, Chromosome, Molecule, and Base Level Arjun Raj, University of Pennsylvania Arjun Raj opened with the most simplistic description of his lab group’s work: “We make tools to visualize gene expression in cells.” He then proceeded to dazzle us with beaut...
The heterochromatin is a condensed type of chromatin that is highly packed and proteins cannot read the DNA. While the euchromatin is not so tightly packed and proteins can conduct the process of DNA description. Similarly, there are active and inactive chromatins that can contribute to transcripti...
Description The Third Edition of Chromatin: Structure and Function brings the reader up-to-date with the remarkable progress in chromatin research over the past three years. It has been extensively rewritten to cover new material on chromatin remodeling, histone modification, nuclear compartmentalization...

These elementary processes involve features at different scales and are already integrated in their formulation. More generally, such a decomposition results in `self-scaled' functional modules, independent of the arbitrary description or observation scale. Self-scaling provides the relevant complexity ...
function (Fig.1f;Supplementary Data2). Among candidate genes,Ppp1r1b(encoding Darpp32) was selected based on its significance for normal brain function and its role in psychiatric disorders, such as schizophrenia and anxiety25,26(Fig.1g). We also found that mRNA expression of this gene varies...
Chromatin is composed of: a) DNA. b) DNA and proteins. c) DNA, RNA and proteins. d) None of the above What is the cellular structure that contains genetic DNA? What is chromatin remodeling? How does it affect chromatin structure and what is its purpose? Include a brief description of ...
We recorded the TMR/JF549-nucleosome dots observed in interphase chromatin and mitotic chromosomes at 50 ms/frame (~450 frames, 22.5 s in total) in living cells (Supplementary movies1and2). The individual dots were fitted with a 2D Gaussian function to estimate the position of the nucl...
