HTTP:: 039 Genome MRI 039 Method Reveals How DNA Packs
--------
As most of you know, unfurling the genetic material enclosed in each of our cells would result in a six-foot-long strand of DNA. However, inside each cell, all this information remains stored within nuclei that are less than three micrometers in diameter, less than the width of a human hair. Finding out precisely how these molecules are crammed into such a tiny space has been something experts have been working on for a long time, and it would appear that the new investigation method has now finally discovered the answer, Technology Review reports. The method can determine the three-dimensional interactions that take place between the various parts of the genome, essentially hinting at how the genetic material and DNA molecules pack themselves inside the nuclei. Previous studies have already determined the 3D structure of several parts of the genome, but the newly developed instrument is the first to do so on a genome-wide scale, its creators say. “Our technology is kin!
d of like MRI for genomes,” Harvard-MIT Division of Health Sciences and Technology researcher Erez Lieberman-Aiden explains. The scientist is also one of the authors of a new paper detailing the find. The thing about DNA is that it not only organizes itself in linear strands and the basic double-helix structures, but also in...
