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 ...

Norgen kits cover a broad range of applications from collection and preservation to isolation and purification. Our expert ...

But when U.S. National Institute of Standards and Technology researchers Christina Bergonzo and Alexander Grishaev put AlphaFold 3 to the test, they discovered that there are cases where the tool’s ...

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 ...

This pathway, or others like it, could explain why some inheritable traits between generations can’t be explained exclusively via DNA and RNA. "There are a lot of traits and disorders that we ...

However, its role as a nucleobase in RNA was not established until the 1940s, when the structure of DNA and RNA was elucidated. The discovery of uracil and its pairing with adenine in RNA was a ...

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.

This type of RNA is called cell-free RNA because the tiny molecules no longer inhabit a cell. There are always fragments of both DNA and RNA floating in blood—byproducts of natural cell death ...
