Chromosome Mapping and Molecular Characterization of the Tc1/Mariner Element in Rineloricaria (Siluriformes: Loricariidae)

ABSTRACT The Tc1/Mariner sequence was isolated and mapped on chromosomes aiming to verify the association of this transposable element (TE) and chromosomal rearrangements in Rineloricaria. Cytogenetic analysis showed that Tc1/Mariner does not co-localize with chromosomal fusion points, in addition the analysis revealed intense molecular degeneration in its DNA sequence.
