Abstract:
Repetitive DNA sequences are interspersed throughout the genomes of mammals and other higher eukaryotes, and represent a substantial portion of the genome. Although it has been generally assumed that the redundant DNA is present only in the complex genomes of high order organisms, over the past few years a number of repetitive DNA sequences have been also detected in the protozoan parasite Trypanosoma cruzi. A compilation of the repetitive DNA sequences found in the T. cruzi genome is here presented by Jose Maria Requena, Manuel Carlos López and Carlos Alonso, who also speculate on their possible origin and functional implications regarding retrotransposition and gene regulation.
