Unexpected slowdowns or spikes in this signal were often interpreted as knots in DNA. But now, a new study published Aug. 12 ...

DNA aptamers are powerful molecular tools in biosensing, bioimaging and therapeutics. However, a limited understanding of ...

In 1957, just four years after Francis Crick and other scientists solved the riddle of DNA’s structure—the now famous double ...

Oregon State University researchers have made significant new advances in determining the structure of all possible DNA sequences -- a discovery that in one sense takes up where Watson and Crick ...

For the first time ever, scientists have identified the existence of a new DNA structure that looks more like a twisted, four-stranded knot than the double helix we all know from high school biology.

The discovery of DNA’s structure unlocked the secrets of genetics, transforming how we understand heredity, evolution and even medicine. ...

The results of this collaborative project overturn some conventional wisdom about how the DNA repair process works.

In 1963, Popular Science reported on the Nobel Prize-winning discovery, and Rosalind Franklin⁠—the woman who was left out of the accolades.

Scientists have a new theory about the structure of DNA. Two strands of alternating sugar (deoxyribose) and phosphate groups make up the DNA double helix, and the strands were thought to be linked by ...

The existence of left-handed DNA (or Z-DNA) was reported in 1979, and marked by a Nature cover. This week's cover story is the determination of the crystal structure of the junction between left ...

Like DNA, each RNA strand has the same basic structure, composed of nitrogenous bases covalently bound to a sugar-phosphate backbone (Figure 1).
