Fig. 2From: First insights on the retroelement Rex1 in the cytogenetics of frogsAmino acid sequence inferred from the nucleotide sequences shown in Fig. 1. Black sites are conserved amino acids. Bars indicate domains 3–7 of the Rex1 RT as determined by Volff and colleagues [8, 9] and Malik and colleagues [37]. Asterisks represent premature stop codonsBack to article page
