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. WebIonizing radiation, which includes X-ray, α, β, and γ radiation as well as charged atomic nuclei, is known to contribute to a variety of genetic diseases and cancers by causing …
Web1 mrt. 2000 · It has long been known that radiation can induce a broad spectrum of DNA lesions including damage to nucleotide bases, cross-linking, and DNA single- and double-strand breaks (DSBs). DSBs were originally assumed to be the critical cytotoxic lesions, whereas base damage particularly thymine glycols were implicated in mutagenesis. 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.
