Each three-letter 'word' of the genetic code in mRNA is called a?

Explanation:
In translation, the genetic code is read in three-nucleotide units on mRNA, called codons. Each codon specifies either a particular amino acid to be added to the growing protein or a stop signal that ends translation. The term codon is the precise name for this three-letter mRNA sequence. A related idea is that tRNA carries an anticodon, a complementary three-nucleotide sequence that pairs with the codon to deliver the correct amino acid, but the anticodon belongs to tRNA, not the mRNA. A nucleotide is just a single base, and while a three-nucleotide unit can be described as a triplet in some contexts, the standard term for the mRNA unit in translation is codon.
