Later, in 1960, the discovery that an RNA molecule and a DNA molecule could form a hybrid ... these RNAs all share the same basic single-stranded chemical structure with, in some cases, higher ...

This discovery, along with the identification of other nitrogenous bases, laid the foundation for our understanding of DNA and RNA structure. Cytosine can be synthesized chemically or isolated from ...

Recent findings indicate that the chirality of molecules, critical to life's structure, might not have been as fixed in early ...

DNA stands for deoxyribonucleic acid. Nucleic acids are named for where they're found—inside the nuclei of cells—and for the ...

Researchers have found an ancient protein fold that might explain how life’s basic building blocks became the complex systems ...

Dynamic, reversible modifications of DNA and RNA regulate how genes are expressed and transcribed, which can influence ...

Recent findings from researchers at UCLA and NASA’s Goddard Space Flight Center are shaking up our understanding of life’s ...

The flexibility of RNA makes it notoriously challenging to study, as its structure can shift into numerous forms depending on ...
