[i] Copies found as of November 27, 1996 with BLASTP <10−25 using the consensus element to search GenBank and the C. elegans Consortium database, at which time ∼80% of the genome sequence was available. The following features are indicated: name of the family, the cosmid in which the initial element was identified, the GenBank accession number for the consensus element sequence derived from several element copies, the size of the full-length element, the minimal number of copies per genome, target site duplication (if any), and the sequence at the termini. In each case, the 5‘ end of the sequence represents the terminus of the element.
