Query: A crystal base for the genetic code   The quantum enveloping algebra U_q(sl(2) \oplus sl(2)) in the limit q \to 0
is proposed as a symmetry algebra for the genetic code. In this approach the
triplets of nucleotids or codons in the DNA chain are classified in crystal
bases, tensor product of U_{q \to 0}(sl(2) \oplus sl(2)) representations. Such
a construction might be compared to the baryon classification from quark
building blocks in elementary particles physics, one of the main differences
standing in the property of a crystal base to provide a natural order in the
state constituents, this order being crucial in the codon. Then an operator
ensuring the correspondence codon/amino-acid can be constructed out of the
above algebra. It will be called the reading operator, and be such that two
codons relative to the same (resp. different) amino-acid(s) acquire the same
(resp. different) eigenvalue(s).
