WebIn contrast to DNA damage, a mutation is a change in the base sequence of the DNA. A mutation cannot be recognized by enzymes once the base change is present in both DNA strands, and thus a mutation cannot be repaired. At the cellular level, mutations can cause alterations in protein function and regulation. WebMutations that go undetected during replication or are the result of a mutagen can be repaired outside of replication. Here are the five repair mechanisms that may be applied: Direct Reversal – Enzymes can directly come and fix the affected region without breaking the phosphodiester DNA bond. download euro coach sim
