Verified step by step guidance1
Understand that mRNA is a type of RNA that carries genetic information from DNA to the ribosome, where proteins are synthesized.
Recognize that the genetic code is read in sets of nucleotide bases on the mRNA, which are crucial for determining which amino acids are added during protein synthesis.
Identify that each set of nucleotide bases that codes for a single amino acid is called a 'codon'.
Recall that a codon consists of three nucleotide bases. This is a fundamental aspect of the genetic code, where each triplet of bases corresponds to a specific amino acid.
Conclude that the correct answer is 'three; codon', as three bases form a codon that specifies an amino acid in the protein synthesis process.
