<span>Some amino acids have multiple different codons that can code for them. So for some point mutations, one wrong nucleotide in a codon may still allow it to code for the same amino acid. For example. Serine has 4 different possible codons which can code for it. UCA, UCC, UCU, and UCG. Note that if the last letter were change in any instance, it would still code for serine. There are MANY other examples for this question; almost all amino acids have more than one codon which can code for it.</span>

Answer:
Buffer
Explanation:
Buffers may be defined as the solution of a weak acid with ithe conjugate base or a weak base with the conjugate acid. Buffers are not affected by the the additions of strong acid or base in a solution.
Whenever a strong base or acid is added to the buffer, it may release or binds with the hydrogen ion and maintains the pH of a body fluid. Blood has a buffer of carbonate ions and bicarbonic acids that maintains the blood pH.
Thus, the correct answer is option (E).
