Using unnatural base pairs, researchers have site-specifically biotinylated RNA, allowing them to immobilize an aptamer on a chip and detect its interaction with a target protein. Experiments with ...

Comparison of a single-stranded RNA and a double-stranded DNA with their corresponding nucleobases. (Image: Wikimedia Commons, CC SA 3.0) The most common type of base pairing is the Watson-Crick base ...

All five nucleobases that make up DNA and RNA have now been detected in meteorite samples ... as terrestrial soil and other environments also contain nucleotide bases. “I think [the researchers] ...

Kossel isolated cytosine from calf thymus tissues and found that it was a component of nucleic acids. This discovery, along with the identification of other nitrogenous bases, laid the foundation for ...

"RNA interference is a well-known type of gene regulation in which cells can turn down the expression of a gene by expressing a small RNA that can base pair with the RNA of the target gene.

When a gene is to be expressed, the base sequence of DNA is copied or transcribed into mRNA (messenger RNA). This process takes place in the nucleus and occurs in a series of stages. The two ...

Editing RNA isn’t all that different from DNA base-editing techniques, which typically use Cas9 or other enzymes attached to a CRISPR guide RNA to replace one nucleotide with another. In the case of ...
