Ribonucleic acid (RNA) is a linear molecule composed of four types of smaller molecules called ribonucleotide bases: adenine (A), cytosine (C), guanine (G), and uracil (U). RNA is often compared ...

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 ...

"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. This type ...

Adenine and guanine, the two most common purines in DNA and RNA, share this core structure, which is crucial for forming the base pairs in nucleic acids. (Image: Wikimedia Commons, Public Domain) ...

"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 ...
