Crack open a biology textbook and you will find a standard icon of molecular biology: the table summarizing the standard genetic code. This refers to the set of rules by which the cell "decodes" the ...

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 ...

A surprising number of microbes use alternate genetic codes, different from the standard genetic code that governs the large majority of life. A census of these "recoded" genomes was recently reported ...

Research suggests that we may have only begun to scratch the surface on the number of variations present in the genetic codes of all living organisms. Crack open a biology textbook and you will find a ...
