The DNA strands used in applications such as the polymerase chain reaction, DNA sequencing, and DNA data storage are typically made using nucleoside phosphoramidite building blocks. These ...

Three meteorites contain the molecular building blocks of DNA and its cousin RNA, scientists recently discovered. A subset of these building blocks had been detected in meteorites before, but the rest ...

(Nanowerk News) Using x-ray crystallography, researchers studied 36 DNA-based molecular junctions and discovered factors that yield superior 3D self-assembled lattice structures (Nature Communications ...

All four of the key DNA building blocks have now been found in meteorites, suggesting that space rocks may have delivered the compounds to Earth, contributing to the origin of life. DNA has a ...

Mitochondria are the energy suppliers of our body cells. These tiny cell components have their own genetic material, which triggers an inflammatory response when released into the interior of the cell ...

This diagram depicts the chemical structure of pyrimidine, a six-membered aromatic ring with two nitrogen atoms at positions 1 and 3 (highlighted in blue). The remaining positions are occupied by ...

In a new study published in Nature Communications, researchers from Stockholm University show for the first time how NrdR binds to DNA to inhibit RNR. The novel mechanism could help scientists design ...

Key building blocks of DNA and RNA can be made from the same raw materials. This finding suggests that instead of one or the other kick-starting life on Earth, both chemicals were involved in the ...

A highly sensitive and easy-to-use technique applicable for tissue samples can be useful, for example, to researchers specialized in mitochondrial diseases and cancer. DNA, or deoxyribonucleic acid, ...
