How do cells correct errors in dna that would disrupt their function?

enzymes use the surrounding sections of the dna to determine the correct structure; then they repair the errors by replacing atoms in the existing molecule.

enzymes cut out the erroneous part and then use the complementary dna on the intact strand to add the correct nucleotides.

enzymes use rna that was made before the damage occurred to make a new double strand of dna to insert into the molecule.

the erroneous part has weaker bonds to the dna molecule, so it falls off, and the proper nucleotides are attracted to the gap to repair the damage
