The findings help explain how about 2 metres of DNA can be neatly packaged in each of our cells, in a space that is about the width of a hair.
Scientists have identified two sets of proteins in cells that work together to keep the strands unknotted, avoiding tangles that would hamper vital biological processes.
Proteins - Organisms - Scientists - Role - DNA
These proteins are found in many organisms, and scientists believe that their role in managing DNA may be common throughout nature.
One family of proteins -- known as SMC -- acts like a belay device used by rock climbers, which passes ropes through a series of loops.
Proteins - Set - TopoII - Tangles - Way
These proteins have been found to work alongside another set, known as TopoII, which was previously thought to help solve tangles, but in a way that was not well understood.
Researchers at the Universities of Edinburgh and Padova in Italy studied the process by creating computer models...
