A
nucleotide
B
amino acid
C
promoter region
D
ribosome
Verified step by step guidance
1
Understand that messenger RNA (mRNA) is a sequence of nucleotides that carries genetic information from DNA to the ribosome, where proteins are synthesized.
Recall that the genetic code is read in groups of three nucleotides called codons.
Each codon corresponds to a specific amino acid or a stop signal during protein synthesis.
Recognize that the role of a codon is to specify which amino acid will be added next in the growing polypeptide chain.
Therefore, the correct interpretation is that each codon in mRNA specifies a particular amino acid.
