WebJun 22, 2024 · A tandem duplication (TD) is an operation on a string S that copies a substring X of S and inserts the copy after the occurrence of X in S. In other words, a TD transforms \ (S = AXB\) into AXXB. Given another string T, we write \ (S \Rightarrow T\) if there exist strings A , B , X such that \ (S = AXB\) and \ (T = AXXB\). WebMay 24, 2016 · A naturally occurring tandem duplication of the Alcohol dehydrogenase (Adh) gene exhibits 2.6-fold greater expression than the single-copy gene in transgenic Drosophila This tandem duplication also exhibits greater activity than two copies of the gene in trans, demonstrating that it is the tandem arrangement and not copy number that is the ...
