Stay Woke, a documentary about the rise of the Black Lives Matter movement, will premiere Thursday on BET. Photo: David McNew/Getty Images Even the most casual social media user has almost certainly seen references to the slang term woke, as in stay woke.
The major lethal lesions are pyrimidine dimers in DNA (produced by UV-B and UV-C)--these are the result of a covalent attachment between adjacent pyrimidines in one strand. This is shown here for a thymine-thymine dimer and here for a thymine-cytosine dimer. third type of spontaneous DNA damage that occurs frequently is damage to the bases by free radicals of oxygen. These arise in cells as a result of oxidative metabolism and also are formed by physical agents such as radiation.
For example, thymine would have a different nitrogenous base than adenine. In addition to this, it also contains one phosphate group and one deoxyribose sugar molecule to complete its signature recipe. Thymine is most often represented as a ring-like structure called a pyrimidine. Each respective base is in the shape of a ring-like form and there are two types. A purine is a base that contains a double ring form. By contrast, a pyrimidine is a base that contains a single ring form. Adenine and guanine are the purines. Thymine and cytosine are the pyrimidines. Adenine and thymine are almost always going to be partners on the DNA ladder. Cytosine and guanine will form the other base pair partnership.
