Ribonucleic acid (RNA) is a linear molecule composed of four types of smaller molecules called ribonucleotide bases: adenine (A), cytosine (C), guanine ... in a chain via chemical bonds called ...

or guanine (G). These mutations can potentially alter the amino acid sequence of the resulting protein, which may affect its function. Pseudouridine is an isomer of uracil, meaning it has the same ...

In a study published recently in Nature Chemical Biology, Weizmann Institute of Science researchers solved the mystery and provided a comprehensive description of the “biological recipes” that cells ...
