Question

A mutation occurs during protein synthesis. How will the protein produced be affected? A. Since the mutation causes a new code for a better amino acid, the protein will still function normally. B. Since the mutation causes a new code for the same amino acid, the protein will still function normally. C. Since the mutation causes a new code for a better amino acid, the protein will be more powerful while performing its function. D. Since the mutation causes a new code for the same amino acid, the protein will be more powerful while performing its function.

Answer 1

Answer:

A mutation during protein synthesis may not affect the protein since the mutation causes a new code for the same amino acid, the protein will still function normally.

Explanation:

Protein synthesis depends on the transcription of DNA to RNA, and on the sequence of nucleotides in the chain, determining the triplets or codons that encode a specific amino acid.

In protein synthesis, when a mutation alters the codon, changing one nucleotide for another, it is possible that the mutation does not alter the amino acid and the protein functions correctly. This is because an amino acid can be encoded by several codons, as occurs with leucine, which is encoded by CUU, CUC, CUA and CUG.

    The other options are not correct because one mutation does not give better amino acids or more powerful proteins.
