Artificial DNA letters beyond A, T, G, C break a fundamental pairing rule to produce nanostructures with new shapes, far greater durability, and an unexpected ability to self-sort. But the four-letter ...

For the first time, researchers have succeeded in developing an artificial DNA base pair that is based on a different chemical force than natural genetic material. While the common natural DNA ...

This image illustrates the chemical structures of the five main nucleobases found in DNA and RNA. The pyrimidines, thymine (DNA), uracil (RNA), and cytosine are shown on top while the purines, adenine ...

DNA is more than just a code—it’s a beautifully precise molecular structure that holds life’s instructions. Understanding its building blocks, base pairing rules, and replication fidelity helps us ...
