it is possible for a mutation to occur and yet not alter the end product of translation if
the mutation affects the active site of the protein product.
a deletion mutation removes the entire codon.
the new codon encodes the same amino acid.
the rna polymerase skips over the mutated area.

Explanation:

• Option 1: If the mutation affects the active site of the protein product, it will likely change the protein's function, so this option is incorrect.
• Option 2: A deletion mutation that removes the entire codon will shift the reading frame for subsequent codons (unless it's a multiple - of - three deletion at the end), which will change the amino acid sequence, so this option is incorrect.
• Option 3: Due to the degeneracy of the genetic code (more than one codon can code for the same amino acid), if a mutation occurs such that the new codon still encodes the same amino acid, the end - product of translation (the protein) will not be altered.
• Option 4: RNA polymerase is involved in transcription, not translation. Also, there is no mechanism for RNA polymerase to "skip" over a mutated area in a way that would prevent a change in the translation product (if the mutation is in the mRNA).

Answer:

the new codon encodes the same amino acid.
