| Sugars are vital components of life, e.g. the 5-carbon sugars ribose and deoxyribose are part of the skeletons of our information storage molecules, RNA and DNA respectively. |
| Certain glycosylases also have abasic lyase activity, cleaving the phosphodiester bond adjacent to the abasic deoxyribose residue. |
| Each nucleotide is composed of deoxyribose, a phosphate group, and one of four nitrogen-containing bases. |
| Other methylations of the bases or of the deoxyribose are sometimes induced by carcinogens. |
| A nucleotide is a combination of a ribose or deoxyribose sugar, a purine or pyrimidine base, and a phosphate group. |
| Strand scission in DNA can result from the production of a carbon-based radical following hydrogen atom abstraction from deoxyribose. |
