Researchers have developed a new technique for imaging cells under an electron microscope that yields a sharper image of the structure of chromatin, the tightly wound bundle of genetic material ...

While the structure of chromatin is proposed to influence gene expression, the authors noted that “the causality relationship between local chromatin fiber conformation and transcription has yet to be ...

Recent observations suggest that the basic supranucleosomal structure of chromatin is a zigzag helical ribbon with a repeat unit made of two nucleosomes connected by a relaxed spacer DNA. A remarkable ...

“If the structure of chromatin changes, it can alter the processing of the information stored in the genome, but it does not alter the genes themselves. Understanding chromatin folding holds the key ...

Chromatin Structure: More Folding, More Complexity Than Expected Date: February 17, 2003 Source: University Of Illinois At Urbana-Champaign Summary: New molecular technologies, some driven by the ...

The results promise to clarify how abnormalities in chromatin structure can contribute to cancers and gene disorders, while also providing inspiration for the development of new types of biodevices.

Chromatin past (a) Thirty-two years later, in 1973, Cold Spring Harbor Laboratory held its next symposium devoted to chromatin — entitled 'Chromosome Structure and Function'.

Belmont, who also is a medical doctor, discussed current trends of research on chromatin structure during a session on "The 'New' Nucleus: Mothership of the Human Genome." Chromatin is a part of a ...

Small basic proteins present in most Archaea share a common ancestor with the eukaryotic core histones. We report the crystal structure of an archaeal histone-DNA complex. DNA wraps around an extended ...

This means that the structure of chromatin itself selectively allows or blocks certain proteins from reaching p53, adding an extra level of regulation beyond simple genetic sequences or protein ...

Although the basic double helix structure of the DNA molecule is known, its three-dimensional organization has continued to elude scientists. Every single cell somehow packs DNA that is two meters ...
