The phrase "a triplet coding for" is correct and usable in written English.
It can be used in the context of genetics or molecular biology to describe a sequence of three nucleotides that specifies a particular amino acid or function.
Example: "The triplet coding for the amino acid serine is UCU."
Alternatives: "a codon specifying" or "a sequence encoding for".
SNP rs228671 is located within the first exon of LDLR in the third position of a triplet coding for amino acid 27, a cysteine (Fig. 2b).
Exceptionally, B. distachyon (G↓GT) contains a triplet coding for the widespread Gly.
During TR, the translational machinery recognizes the stop codon of the nonsense mutation as a triplet coding for an amino acid resulting in the translation of a full-length protein from mutant messenger RNA (mRNA; Fig 1A).
In addition, the alternative use of a noncanonical TG 3′-splice site preceding exon 4 can result in the inclusion of an extra triplet coding for a serine residue after amino acids 87 and 72 of the long and short forms of Gs-alpha, respectively.
The first event leads to deletion of a nucleotide triplet coding for glutamic acid (validated by one cDNA clone sequence out of 12 random clones analyzed), yet with no effect on the functional domains.
The 5 kb PCR product was TOPO cloned into pENTR/D-Topo (Invitrogen, USA) and the CCG triplet coding for proline at position 144 within AapQ replaced by a GAC coding for aspartic acid (P144D) using the Quick Change site-directed mutagenesis kit (Stratagene, USA).
The genomic sequences of the VvSTS genes detected in the PN40024 genome ranged in size from a minimum length of 1315 nt (VvSTS16) to a maximum of 1566 nt (VvSTS1) depending on the length of the single introns present in all members within the triplet coding for Cys-60.
In this sense, the existence of a triplet code may be no accident of early evolution.
The four-column code is a triplet code, although only the middle base in the codon specifies any information.
Fourthly, this paper supposes that the code was always a triplet code, but that the three letters may not all have encoded information initially.
People were still trying to figure out what DNA triplet coded for which amino acid, and Jim Watson would come rushing into class waving triplets.
