Abstract
Genome size is constant to a species, differences in species is brought out by genome size variation. Changes in the genome size is mainly by the changes in the copy number driven by the various repetitive sequences. Transposons are the kind of repetitive sequences put forth the genome size variation by its mobility characteristics within the genome causes a great variation even closely related species. Studying the structure and functions of transposons is necessary to understand the mechanism of genome size variation and thereby it is possible to study the species relatedness in the evolutionary history.
