A protein called PriC allows DNA replication to proceed in Escherichia coli when the complex that usually initiates this process is compromised.

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 ...

New research predicts the location of DNA sequences that can form structures besides the canonical double helix — non-B DNA — in the recently released telomere-to-telomere genomes of the great ...

When Watson and Crick reported the double helix in 1953, they gave the scientific community a breakthrough understanding of how genetic information is stored and copied. For DNA to replicate ...

While six years ago they found that these so-called SMC motor proteins make long loops in our DNA, they now discovered that these motors also put significant twists into the loops that they form.

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 ...

Royalty-free licenses let you pay once to use copyrighted images and video clips in personal and commercial projects on an ongoing basis without requiring additional payments each time you use that ...

Rachel Brazil reports Biology encodes its genetic instructions in sequences of base pairs within the backbone of DNA’s right-handed double helix and through the RNA ... ‘I would go to meetings and put ...

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 ...

Seventy years ago, a trio of scientific papers announcing the discovery of DNA’s double helix was published. Watson, Crick and Wilkins won the Nobel Prize in physiology or medicine in 1962 for ...
