WebSugar-phosphate backbone forms the structural framework of nucleic acids, including DNA and RNA. Sugar phosphates are defined as carbohydrates to which a phosphate group is … WebJan 28, 2013 · High-energy ionizing radiation can blast through the sugar-phosphate backbone. This causes either single-strand breaks (SSB) or double-strand breaks (DSB). For SSBs, the first step is detection of the break. That’s the job of an enzyme called poly (ADP-ribose) polymerase (PARP). This enzyme signals other repair proteins to come to the break. sharing violation retry limit reached

WebDec 18, 2016 · First, let’s take a look at the sugar-phosphate backbone of a nucleic acid. At the center of every nucleic acid is the sugar-phosphate backbone. The phosphate group forms phosphoric acid in water. This phosphate group can bond to the sugar molecule on the next nucleic acid, creating a long chain. ...
