The genome size in eukaryotes does not correlate well with the number of genes they contain. We can observe this so-called C-value paradox in amphibian species. By analyzing an amphibian genome we asked how repetitive DNA can impact genome size and architecture. We describe here our discovery of a Tc1/mariner miniature inverted-repeat transposon family present in Xenopus frogs. These transposons named miDNA4 are unique since they contain a satellite DNA motif. We found that miDNA4 measured 331… CONTINUE READING
