Aligned sequences of the cloned fragments of Engystomops freibergi (5SACR) and Engystomops petersi (5SYAS and 5SPUY). A. Type I 5S rDNA sequences. B. Type II 5S rDNA sequences. The shaded areas indicate the presumed transcribing regions. The annealing sites of the primers used in this study are shown. Presumed regulatory elements are indicated (A box, IE, C box, poly-T, TATA box, TATA-like, hexanucleotides AGAAGC and GCAAGT, and GAACAAA sequence). The arrow in A points to the C nucleotide at position -1 in all the type I sequences. A microsatellite observed in type II sequences is also indicated in B.
