Scientists found that DNA’s phosphate groups can direct chemical reactions to make the correct mirror-image form of drug ...

Proceedings of the National Academy of Sciences of the United States of America, Vol. 90, No. 8 (Apr. 15, 1993), pp. 3363-3367 (5 pages) Homothallic switching of yeast mating type (MAT) genes is a ...

Because I find it hard to relate to something as small as the structure of the human genome, I like to imagine it scaled up a millionfold. At this size, each DNA molecule—a chromosome—is as wide as a ...

Like its viral cousins, a somewhat parasitic DNA sequence called a retrotransposon has been found borrowing the cell's own machinery to achieve its goals. In a new work appearing online Wednesday in ...

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, ...

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.

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 ...
