The alternative yeast nuclear code (translation table 12) is a genetic code found in certain yeasts. However, other yeast, including Saccharomyces cerevisiae, Candida azyma, Candida diversa, Candida magnoliae, Candida rugopelliculosa, Yarrowia lipolytica, and Zygoascus hellenicus, definitely use the standard (nuclear) code.

Bases: adenine (A), cytosine (C), guanine (G) and thymine (T) or uracil (U).
