WebAug 8, 2024 · DNA is the template from which everything inside the human body is built, so it is incredibly important that nothing happens to this code. Unfortunately, the DNA is at constant risk of mutation, which means a change to the genetic information in a cell, and this can happen due to a variety of factors.[1] WebPyrimidine dimer (PD) is, perhaps, the best-known DNA lesion affecting a single DNA strand. It is an intrastrand cross-link, in which two adjacent pyrimidines are connected by a cyclobutane ring. Most frequently, such dimers form between two thymines (Figure 1) – hence, an alternative name ‘thymine dimer’, but dimers between a thymine and a …
