Echinoderm and flatworm mitochondrial code
The Echinoderm and Flatworm Mitochondrial Code is a variant of the genetic code used by the mitochondria of certain echinoderms and flatworms. This code is one of several mitochondrial genetic codes that differ from the standard genetic code.

Differences from the Standard Genetic Code[edit | edit source]
The Echinoderm and Flatworm Mitochondrial Code differs from the standard genetic code in the following ways:
- The codon UGA, which is a stop codon in the standard code, codes for tryptophan (Trp) in this mitochondrial code.
- The codons AGA and AGG, which code for arginine (Arg) in the standard code, code for serine (Ser) in this code.
