Web19 jul. 2024 · They can cause a number of chemical changes in DNA, including directly break phosphodiester backbone of DNA, leading to deletions. Ionizing radiation can also break open the imidazole ring of purines. Subsequent removal of the damaged purine from DNA by a glycosylase generates an apurinic site.

Web28 jan. 2013 · Sometimes, radiation damages a single base on one strand of DNA. This can occur chemically when a hydroxyl (OH-) free radical reacts with a hydrogen atom and forms hydrogen peroxide (H 2 O 2 ). It is fairly easy to repair damage like this if the complementary (or opposite) strand is undamaged. Web2 feb. 2016 · Ionizing radiation (IR), like X-rays and gamma-rays, is commonly used for the treatment of cancer because it has the ability to pass through tissues and can break chemical bonds and help in the removal of electrons from atoms to get ionized. The ionized ions as a result damage cancer cells.
