Blue sharks can change colour like chameleon, scientists find - Study finds skin colour of blue shark grows darker when it ...

New research into the anatomy of blue sharks (Prionace glauca) reveals a unique nanostructure in their skin that produces ...

We also report the first high-resolution structure of a Bateman domain bound to guanine nucleotides and describe the structural determinants that dictate adenine or guanine nucleotide binding.

Guanine is a crucial nucleobase in DNA and RNA, forming stable base pairs with cytosine and playing key roles in genetic information storage, gene regulation, and energy metabolism.

Previous attempts to make such multi-terminal charge-transfer structures from DNA relied on double crossover motifs, but charge cannot flow between the helices of these structures, he explains. To try ...

Guanine crystals. The shape of the reflective crystals, it turns out, is an important part of natural mirrors found within scallop eyes.

Guanine, being widely present in the biogenic photonic structures of various living organisms, exhibits diverse shapes and sizes, including hexagonal plates, square plates, irregular polygons, and ...

Base Editing Now Able to Convert Adenine-Thymine to Guanine-Cytosine With the arrival of a new class of single-nucleotide editors, researchers can target the most common type of pathogenic SNP in ...

Guanine nanocrystals the secret to chameleon's changing colors Previous studies suggest chameleons that can change colors faster and display more vivid combinations are more successful in finding ...

Scientists have detected adenine and guanine in meteorites for decades and seen hints of uracil. But cytosine and thymine had remained elusive.

In the new study, Lia Addadi and colleagues note that researchers have known for years that guanine crystals in the skin underneath the scales of fish reflect light to produce a mirror-like sheen.
