Later it was found that the sugar in nucleic acid can be ribose or deoxyribose, giving two forms: RNA and ... This way DNA can reproduce itself without changing its structure -- except for ...

A History in Hybridization and Structure Alexander Rich and David Davies discover the double-stranded RNA helix and show that polyribo U and polyribo A hybridize spontaneously.6 Ben Hall and Sol ...

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 ...

In the process, DNA is transcribed into RNA and then translated into functional proteins that subsequently undergo folding to achieve their correct structure, which is key to proper function.

Enzymes called RNA polymerases transcribe DNA into RNA. RNA is the intermediary that carries ... X-ray diffraction crystallography data into a 3D representation of the structure of this enzyme.

In the process, DNA is transcribed into RNA and then translated into functional proteins that subsequently undergo folding to ...

They have determined the molecular structure of one of the Tas proteins ... A family of modular RNA-guided DNA-targeting systems in prokaryotes and their viruses, Science (2025).

In some, the RNA-binding region is adjacent to a DNA-cutting part of the protein ... They have determined the molecular structure of one of the Tas proteins they found to work in human cells ...
