{{Short description|Nuclear genetic code in some ciliates}}
The '''peritrich nuclear code''' (translation table 30) is a genetic code used by the nuclear genome of the peritrich ciliates ''Vorticella'' and ''Opisthonecta''.<ref>{{Cite journal|last1=Sánchez-Silva|first1=Rocı́o|last2=Villalobo|first2=Eduardo|last3=Morin|first3=Loı̈c|last4=Torres|first4=Antonio|year=2003|title=A New Noncanonical Nuclear Genetic Code|journal=Current Biology|volume=13|issue=5|pages=442–447|doi=10.1016/s0960-9822(03)00126-x|pmid=12620196|s2cid=17484731|doi-access=free}}</ref>
==The code (30)== :<code> AAs = FFLLSSSSYYEECC*WLLLAPPPPHHQQRRRRIIIMTTTTNNKKSSRRVVVVAAAADDEEGGGG</code> :<code>Starts = --------------*--------------------M----------------------------</code> :<code> Base1 = TTTTTTTTTTTTTTTTCCCCCCCCCCCCCCCCAAAAAAAAAAAAAAAAGGGGGGGGGGGGGGGG</code> :<code> Base2 = TTTTCCCCAAAAGGGGTTTTCCCCAAAAGGGGTTTTCCCCAAAAGGGGTTTTCCCCAAAAGGGG</code> :<code> Base3 = TCAGTCAGTCAGTCAGTCAGTCAGTCAGTCAGTCAGTCAGTCAGTCAGTCAGTCAGTCAGTCAG</code>
Bases: adenine (A), cytosine (C), guanine (G) and thymine (T) or uracil (U).
Amino acids: Alanine (Ala, A), Arginine (Arg, R), Asparagine (Asn, N), Aspartic acid (Asp, D), Cysteine (Cys, C), Glutamic acid (Glu, E), Glutamine (Gln, Q), Glycine (Gly, G), Histidine (His, H), Isoleucine (Ile, I), Leucine (Leu, L), Lysine (Lys, K), Methionine (Met, M), Phenylalanine (Phe, F), Proline (Pro, P), Serine (Ser, S), Threonine (Thr, T), Tryptophan (Trp, W), Tyrosine (Tyr, Y), and Valine (Val, V).
