Recall that a codon is a sequence of nucleotides in mRNA that specifies a particular amino acid during protein synthesis.
Understand that each codon is made up of a specific number of nucleotides, which are the basic building blocks of nucleic acids.
Remember that the genetic code is read in triplets, meaning each codon consists of three nucleotides.
Recognize that these three nucleotides together code for one amino acid or a stop signal during translation.
Therefore, the number of nucleotides composing a codon is 3.
