Clustering of the inversion points. The L1 RNA is represented by a black line ending in a poly(A) tail (A(n)). The position on the RNA is numbered from the first nucleotide (1) to the end of the AATAAA poly(A) signal (6022). The region of the L1 RNA from nucleotides 4000–6000 is expanded on the line above. A black arrow represents the inversion point of each element. Each inversion is labeled with its accession number and the position of its inversion point.
