Effect of defects on thermal denaturation of DNA Oligomers
... chains of heterogeneous compositions. A defect on DNA chain means a mismatched basepair. For example, if one strand of DNA has adenine on a site the other strand has guanine or cytosine instead of thymine on the same site. In such a situation the pair will remain in open state at all temperatures as ...

Summary/Reflection of Dan Freedman`s article, Science Education
... A thymine dimer, for example, originates when two adjacent thymine nucleotides in the same strand base-pair with each other instead of with the adenine bases in the complementary strand. 2. Such errors can be fixed by excision repair enzymes that splice out the error and use the complementary strand ...
