Question

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

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.

Enzymes cut out the erroneous part and then use the complementary DNA ​on the intact strand to add the correct nucleotides.


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 use​ RNA ​that was made before the damage occurred to make a new double strand of DNA ​to insert into the molecule.
