DNA's double helix has long stood as the symbol of life’s code. But buried within the genome lies a deeper level of complexity. One of the more intriguing discoveries in recent years is the i-motif—a ...

Geometry describes an object at a particular ... coli and other bacteria, the DNA double helix closes into a circle, like a twisted rubber band. Replication of the E. coli chromosome can happen ...

An international team of scientists, composed of researchers from the Complutense University of Madrid, Saint Louis University’s Madrid campus, and the University of California, has proposed a new ...

The 5-formylcytosines directly affect the geometry of the stacking of ... a change in the physical properties of the DNA double-stranded helix. Although 5fC did not affect the thermodynamic ...

Inside the cell’s nucleus, the double helix folds up in ... for unveiling genomic geometry. “Now we are going back to studying the structure of the genome because we realize that the three-dimensional ...

More than seven decades later, mathematician Robert Monjo believes he has discovered a similarly significant double helix — but this time not as the structure of human DNA, but as the structure ...

This organization can be explained by weak interactions between nucleosomes, which are the repetitive blocks that fold the ...

The discovery of DNA's double helix structure 70 years ago opened up a world of new science — and also sparked disputes over who contributed what and who deserves credit. Much of the controversy ...

If you were asked to picture a molecule of DNA, chances are you would visualize a long, straight, right-handed double helix—the type you were taught in science class. It's well established that ...

and special proteins attach to DNA to mechanically unwind the double helix and then pry it apart. "The interior of the cell is super crowded with molecules, and most biochemistry experiments are ...

Certain DNA sequences can form structures other than the canonical double helix. These alternative DNA conformations—referred to as non-B DNA—have been implicated as regulators of cellular ...
