Answer:
Silent mutations do not affect protein function
Explanation:
A mutation is defined as any alteration in the genetic material of a cell of a living organism. Moreover, a silent mutation refers to any mutation that does not alter the phenotype of the cell/organism (they are evolutionary neutral mutations). Silent mutations are base substitutions that do not alter the amino acid sequence of the resulting protein, and therefore these mutations do not alter protein function.
