exon

codon

anticodon

intron

Verified step by step guidance

Understand that the question is asking about the sequence in mRNA that specifies each amino acid in a protein.

Recall that mRNA is composed of nucleotide bases arranged in groups of three, which are called codons.

Each codon corresponds to a specific amino acid or a stop signal during protein synthesis.

Differentiate codons from other terms: exons are coding regions in DNA/RNA, introns are non-coding regions, and anticodons are sequences in tRNA that pair with codons.

Conclude that the correct term for the three-base sequence in mRNA that specifies an amino acid is a codon.
