Picture in your mind a traditional “landline” telephone with a coiled cord connecting the handset to the phone. The coiled telephone cord and the DNA double helix that stores the genetic material in ...
When people think of DNA, they visualize a string-like double helix structure. In reality, the DNA double helix in cells is supercoiled and constrained into loops. This supercoiling and looping are ...
Even living cells have their own tangled problems to solve. They involve knots that arise accidentally in DNA and that can comprise its functionality. A new study by SISSA (Scuola Internazionale ...
Researchers from Durham University, Jagiellonian University (Poland) and the John Innes Centre have achieved a breakthrough in understanding DNA gyrase, a vital bacterial enzyme and key antibiotic ...
DNA (deoxyribonucleic acid), the molecular "blueprint" carrying the genetic instructions that influence the growth, development, reproduction and predispositions of individual humans, can undergo ...
Supercoiling and looping can transmit mechanical stress along the DNA backbone that can promote the separation of the strands of the double helix at specific distant sites, exposing the DNA bases, ...
A team of physicists working at the intersection of theory and experiment are shedding new light on the 'teamwork' of molecular motors -- called RNA polymerases (RNAPs) -- that mediate DNA ...

If you uncoiled the DNA in one cell, it would stretch about two meters
Every human cell packs roughly two meters of DNA into a nucleus only six micrometers wide. That ratio, confirmed by ...
