Failure of the DNA repair mechanism can result in cancer, mutation or a defective enzyme.
The differences are as follows: Mismatch repair DNA polymerase is the enzyme that is responsible for DNA replication. As it copies the the DNA, it can make mistakes. So, when the DNA is copied, mismatch repair proofreads it and makes sure that the nitrogenous bases are correct. If they aren't, then it will take out only the base. However, if the mismatch repair is not functioning, then humans can get some form of cancer. Excision repair This mechanism is caused by UV rays or some sort of harmful chemical. Excision repair fixes what portion may have been destroyed by these mutagens. It takes the entire strand and replaces it with a new one. However, if this mechanism doesn't work, then forms of skin cancers arise.

A mutation occurs, and cancer can form since mutations are occurring quicker than repair is able to take place. There could also be a defective enzyme
no replication makes a whole new strand of identical DNA while repair just replaces or cuts out mutations in the DNA strand
nothing
Mutagens cause a change in DNA and by this way they can produce mutant DNA repair enzymes.
