Some mutations or changes in the sequence of DNA, do not have any offect on the characteristics of the organism. Why Is this? The protein from this mutated sequence deactivated by the cell The mutated sequence still codes for the same amino acid The cell recognizes mutations and ignores them when expressing the gene The immune system repairs the mutated sequence during development
