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

Thus, far from being junk DNA, this is better called functioning DNA, though many of its functions are still being discovered. There are several types of non-coding or junk DNA.

In a world first, researchers have identified a new DNA structure -- called the i-motif -- inside cells. A twisted 'knot' of DNA, the i-motif has never before been directly seen inside living cells.

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

DNA incorporating Diaminopurine is called Z-DNA. We've known since 1979 that it exists in nature in the form of a single virus called S-2L, which infects cyanobacteria.

For the first time, scientists at the University of North Carolina at Chapel Hill have successfully created a liquid form of DNA, the complex helical molecule that serves as the blueprint for ...

We are used to thinking of DNA in the form of Watson and Crick's double helix, but a new study suggests there may be different shapes of DNA.

Scientists have identified an entirely new kind of DNA inside humans. This new DNA, known as the “i-motif,” was suggested in previous research, but had only been identified under artificial ...

It contains dynamic DNA modifications that carry key inheritable epigenetic information passed among generations of cells,” said He, the John T. Wilson Distinguished Service Professor in Chemistry and ...
