About MolGenT	Repair Of UV Damage The sun gives off UV radiation that can damage DNA by inducing the formation of bonds between adjacent thymine bases. This type of damage is called a thymine dimer and causes a bulge to appear in the double helix, obstructing the normal DNA replication process and resulting in changes or mutations in the DNA sequence. However, UV damage can be repaired by special repair enzymes, including an endonuclease that excises the region of DNA containing the thymine dimer. Once the dimer has been removed, DNA polymerase fills in the gap with fresh nucleotides and another enzyme called DNA ligase seals the new segment of DNA into the repaired strand.
