Cells can protect themselves from things that cause mutation and they also have mechanisms for repairing mutation. However, it is important to keep in mind that a mutation could be beneficial, so even if an organism could avoid any and all mutations, that species would never evolve and would eventually be out-competed by a species that would evolve. read more

Cells Protect Themselves from Damage to Their DNA. The cell has many mechanisms to ensure that each DNA molecule replicates to form an identical copy. In addition, cells contain certain proteins (“spell-checkers” and “proof-readers”) that make sure that there are no “spell-ing” errors, or mutations in the nucleotide sequence before DNA replication.
