The structure of each inversion. A full-length L1 element is represented by the hashed line, numbered from the first nucleotide (1) to nucleotide 6000 near the end of the sequence. The structure of each inversion is represented below the schematic L1. A left-facing arrow represents noninverted sequence with the length denoted above (distance from the AATAAA poly(A) signal to the end of the noninverted sequence). A right-facing arrow represents inverted sequence with the length denoted above (distance from the inversion point to the target site duplication). For example, the sequence at the tail of the inverted sequence from Z95325 is represented on the L1 consensus sequence near nucleotide 5450, and the sequence at the head of the arrow is represented near nucleotide 1380. Each inversion has nucleotides from the consensus sequence either deleted (del) or duplicated (dup) at the end of the noninverted sequence (head of left-facing arrow). The size of the deletion or duplication is indicated above its corresponding location relative to the L1 consensus sequence. Note that in the case of a duplication, the duplicated sequence is located both in its usual univerted position at the end of the noninverted sequence (head of the left-facing arrow) and also is inverted at the beginning of the inverted sequence (tail of right-facing arrow). Most inversions have evidence of complementary nucleotides at the inversion junction that could be associated with either the end of the noninverted sequence (head of left-facing arrow) or the end of the inverted sequence (head of right-facing arrow). The number of complementary nucleotides is indicated in brackets under the column labeled “Overlap.” In the case of complementary nucleotides, the sizes of the inverted sequence, the noninverted sequence, and the deletion or duplication become variable, as indicated by the numbering. In one case there are no complementary nucleotides [0], and in two cases there are a number of nontemplated nucleotides. A negative number in brackets indicates the number of nontemplated nucleotides, and the nontemplated nucleotides are listed in parentheses.
