In everyday life, our genetic material is constantly under attack from many factors. Environmental influences such as light, ...

DNA can be used as a building block for future molecular-scale electronic circuits because it can form a variety of 3D structures and networks. Thanks to a new three-terminal electronic circuit ...

Scientists from Fuzhou University obtained a set of nanocarbons through self-assembling guanine molecules. Besides exhibiting intriguing properties, including relatively stable surface oxygen groups ...

However, the exact shape of these guanine crystals and how they work remained a mystery. The researchers extracted guanine crystals from the skin of the Japanese Koi fish and analyzed the crystals ...

Colour changes in chameleons are due to structural changes inside skin cells and not chemistry It’s all about guanine nanocrystals. What? Guanine nanocrystals. Many chameleons are capable of ...

Guanine nucleotide exchange factors (GEFs) are pivotal regulators of small GTPases that orchestrate membrane traffic, a process fundamental to organelle function and intracellular communication. By ...

Biogenic guanine crystals are naturally occurring photonic structures that underpin a range of optical phenomena in the biological world. These crystals, formed within specialised cells, exhibit ...

A screenshot of a Google Doodle, which is drawn in light and dark purple and shows a cartoonish DNA double helix, the structure of guanine and a phosphate group, and small cartoons of a chromosome and ...

For scientists attempting to understand how the building blocks of RNA originated on Earth, guanine has proven to be a particular challenge. By adding UV light to a model prebiotic reaction, ...
