This circular diagram represents the genetic code, showing how the four nucleotide bases of RNA (adenine [A], cytosine [C], guanine [G], and uracil [U]) form codons that specify amino acids. Each ...

Scientists have long believed that a universal genetic code serves as a blueprint for all life on Earth, dictating the structure and function of organisms from the simplest bacteria to complex humans.

DNA consists of a code language comprising four letters which make up what are known as codons, or words, each three letters long. Interpreting the language of the genetic code was the work of ...
