Metal-mediated base pairing in nucleic acids represents a transformative approach wherein traditional Watson–Crick hydrogen bonds are replaced or supplemented by coordinate bonds with metal ions. This ...

Structural comparison of DNA and the artificial TNA, a Xeno nucleic acid with the natural base pairs AT and GC and an additional base pair (XY). The DNA carries the genetic information of all living ...

Three free radicals have been detected in single crystals of a molecular complex between 1-methylcytosine (1MeC) and 5-fluorouracil (5FU) X-irradiated and observed by ESR at 77 K. One of these ...

Base pairs are at the heart of molecular biology information. Recognized ever since their discovery by Watson and Crick in 1953, the base pair provides, among other things, rules for copying DNA, ...

Billions of years ago, when the Earth was in its infancy and biology hadn't even gotten going, the precursors to the first living organisms were probably self-replicating strands of RNA. Scientists ...

Carnegie Mellon University researchers have developed a synthetic molecule that can recognize and bind to double-stranded DNA or RNA under normal physiological conditions. The molecule could provide a ...

Named after the two-faced god, newly developed Janus nucleic acid recognition elements target double-stranded DNA or RNA by engaging both strands at once. When strung together within a single-stranded ...

The genome of every cell on Earth uses four DNA bases—adenine, thymine, cytosine, and guanine—to encode proteins. Chemists have long dreamed of expanding that set to create cells that work with both ...

Nucleotides are the building blocks of the two nucleic acids, ribonucleic acid (RNA) and deoxyribonucleic acid (DNA). As such, they are also the building blocks of you and every other lifeform on ...
