Question

reviewing the genetic code
the genetic code is based on sequences of three bases called codons
codons form a unit of the genetic code that determines a specific .

Explanation:

In molecular biology, codons are triplets of nucleotides (bases) in mRNA. Each codon corresponds to a specific amino acid (or a start/stop signal in translation). This is fundamental to the central dogma of molecular biology (DNA → RNA → protein), where the genetic code (codons) dictates the sequence of amino acids in a protein.

Answer:

amino acid
