Question
What is DNA repair?
Solution
DNA Repair: How is genomic stability maintained in all living organisms? How do organisms on earth survive? What is essential for their survival?
DNA is unique because it is the only macromolecule where the repair system exists, which recognizes and removes mutations. DNA is subjected to various types of damaging reactions such as spontaneous or environmental agents or natural endogenous threats. Such damages are corrected by repair enzymes and proteins, immediately after the damage has taken place. DNA repair system plays a major role in maintaining the genomic/genetic integrity of the organism. DNA repair systems protect the integrity of genomes from genotoxic stresses.
