Ciliate, dasycladacean and hexamita nuclear code

 The ciliate, dasycladacean and Hexamita nuclear code (translation table 6) is a genetic code used by certain ciliate, dasycladacean and Hexamita species.

The ciliate macronuclear code has not been determined completely. The codon UAA is known to code for Gln only in the Oxytrichidae.
