Integrity, precise duplication and passing of primary genetic information to the next generation are as important as the moderate change of the genetic material called mutation. DNA is the most precious macromolecule of the cell. This cellular heteropolymer can be repaired in vivo. Cellular DNA repair is important since inherent lesions are multiplied in the processes of genetic information transfer and appear in the form of many imperfect RNA and even more protein molecules. This imperfection costs extra energy. Cells are economical systems, excess energy consumption puts them under selective pressure. Repair processes are responsible for maintaining DNA information. Although, DNA replication itself has some repair function, in this chapter we deal with DNA corrections commonly known as repair processes.
