The translation process will result in the creation of proteins. The process of protein synthesis is controlled by messenger RNA, or mRNA. Activation, initiation, elongation, and termination are the four phases in the translation process in a normal cell. Mutation is a phenomenon in which the nucleotides of the DNA sequence are altered or deleted as a result of carcinogen exposure. A frameshift mutation causes an error in the mRNA soon after the start of translation with AUG or methionine, and this mutation has a significant impact on polypeptide products.a. a codon deletion — This option is incorrect because a codon deletion does not cause an mRNA error.c. an ACC codon substitution of the third nucleotide — This option is incorrect because it occurs as part of the base pair substitution mutation.D. a codon insertion —This option is incorrect because a codon insertion does not result in an mRNA error. E. a substitution of a CUA to UUA — This option is incorrect because it has only a minor impact on polypeptide products. Option B is correct. A deletion of two nucleotides.
