What have we learned about RNA structure and function so far ... Later, in 1960, the discovery that an RNA molecule and a DNA molecule could form a hybrid double helix was the first experimental ...

Our DNA is constantly under threat — from cell division errors to external factors like sunlight and smoking. Fortunately, ...

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 ...

But James Watson and Francis Crick's claim was a valid one, for they had in fact discovered the structure of DNA, the chemical that encodes instructions for building and replicating almost all ...

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 ...

Genes have to be expressed in the right place, at the time, and at the right levels. Scientists wanted to know more about how ...

A vast search of natural diversity has led scientists at MIT's McGovern Institute and the Broad Institute of MIT and Harvard to uncover ancient systems with the potential to expand the genome-editing ...

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.

Researchers use high-resolution imaging to reveal the dynamic structure of biomolecular condensates, shedding light on their ...
