Genetics found in the DNA of a human "Ghost" glow

American genetics from northwestern University announced the discovery of human DNA is unusual glow, which they describe as a "Ghost".

As stated in the article, published in the journal Proceedings of the National Academy of Sciences, we are talking about the ability of DNA molecules to emit soft light.

In the message the scientists also stated that the opening of such fluorescent properties of molecules can be used as natural mechanism of rendering various genetically determined processes. Currently, for these purposes, scientists use a variety of third-party substances, for example, they can take protein compounds, which give the green light that allows you to add clarity.

However, the opening to relieve the scientists from this need, since all of the components to include its own "illumination" is already there in the DNA just need to activate them in a special way.

Fluorescent fotoprilozheny native, unmodified deoxyribonucleic acid (DNA) using a nanometer of visible light facilitates the visualization of chromatin structures without labels based on the principle of one-molecular photon localization microscopy (PLM). With a demonstrated resolution better than 20 nm DNA-PLM is a perfect method to visualize the spatial organization of individual or groups of nucleosomes and quantitative assessment of the level of employment unpainted DNA in chromosomes and nuclei.

This study opens the way to identify the nanoscopic features of the chromatin without the need of exogenous labels, and may significantly expand our understanding of the structure-function relationship of chromatin.
