Scientists have found that twisting structures in DNA long mistaken for knots are actually something else entirely. Inside cells, DNA gets twisted, copied, and pulled apart. The twists can influence ...

Researchers explore a basic building block used in the fabrication of many DNA nanoforms. Known as a Holliday junction, this nexus of two segments of double stranded DNA has been used to form ...

DNA is the genetic material used by every living organism. But, in a few edge cases, the four bases of DNA—adenine, thymidine, cytosine, and guanine—undergo chemical modifications. And in viruses, ...

PORTLAND, Ore. — Using DNA's unique lock-and-key mode of chemical bonding, a research team at the University of Minnesota is proposing a molecular-circuit assembly technique that they believe will be ...

A group led by researchers at Baylor College of Medicine has identified significant differences at the epigenetic level – the chemical tags in DNA that help regulate gene expression – between two ...

WASHINGTON -- It has been 50 years since scientists first created DNA in a test tube, stitching ordinary chemical ingredients together to make life's most extraordinary molecule. Until recently, ...

Scientists from the RNA Institute at the University of Albany (UAlbany) have developed new methods for designing and assembling DNA nanostructures that enhance their potential for use in various ...
