Types of DNA Repair -
Mismatch repair
Base excision repair
Nucleotide excision repair
Direct repair
Homologous recombination and Non-homologous end-joining repair

The mechanisms used for the repair of DNA involve:
First recognition of distorted region of the DNA.
Secondly removal or excision of the damaged region of the DNA strands.
Then filling of gap left by the excision of the damaged DNA by DNA polymerase.
Finally sealing the nick in the strand that has undergone repair by a ligase
