Verified step by step guidance

Understand that a codon is a sequence of nucleotides in mRNA that codes for a specific amino acid during protein synthesis.

Recall that the genetic code is read in groups of nucleotides, where each group corresponds to one amino acid or a stop signal.

Recognize that the standard length of a codon is three nucleotides, which allows for 64 possible combinations (4 nucleotides raised to the power of 3).

Note that this triplet nature of the codon is universal in almost all organisms and is fundamental to translating genetic information into proteins.

Therefore, the number of nucleotides that make up a single codon is three.
