Introduction
Recently, there has been increasing interest in the damage of DNA, which may cause various diseases such as cancer. (1-5) DNA is made of thymine (T), cytosine (C), guanine (G), and adenine (A). The nucleic-acid bases store the genetic information for cell replication and synthesis of proteins. Their physical chemistry has been extensively studied both experimentally and theoretically. In these bases, the thymine is the simplest pyrimidine base and only exists in DNA, not in RNA. It has been a highly frequent subject of theoretical studies because of its biochemical importance. (6,7) One of the possible molecular mechanisms for the formation of ...
