Question

a dna mutation results in a protein that is the same as the initial protein synthesized before the mutation. which statement best explains this outcome? a one amino - acid substitution does not affect protein synthesis. b different codons can be translated into the same amino acid, so some mutations do not affect the protein. c only mutations that occur at the chromosomal level change protein function. d amino acids have similar functions, so their corresponding proteins are unaffected by mutations.

Explanation:

The genetic code is degenerate, meaning different codons can code for the same amino - acid. So, a DNA mutation that changes a codon may not change the amino - acid incorporated into the protein during translation, resulting in no change to the protein structure and function.

Answer:

B. Different codons can be translated into the same amino acid, so some mutations do not affect the protein.
