Figure 7From: R2 and R2/R1 hybrid non-autonomous retrotransposons derived by internal deletions of full-length elementsThe 5' ends of Drosophila immigrans elements function as ribozymes. (A) Folded RNA secondary structures, J1/2 sequencers, and highlighted nucleotides for R2Dim and R2/R1Dim_SIDE are as described in Figure 4. (B) In vitro cotranscription/cleavage assay as described in Figure 4.Back to article page
