Multiple sequence alignment of deduced amino acid residues of the reverse transcriptase (RT) domain of Sinbad and six other Pao-like elements. Numbered blocks delineated by green brackets correspond to the seven conserved blocks of RT residues as described by Xiong et al. . Identical and chemically similar residues are boxed and shaded.
