Structure of the highly repeated, long interspersed DNA family (LINE or L1Rn) of the rat.

摘要: We present the DNA sequence of a 6.7-kilobase member rat long interspersed repeated family (LINE or L1Rn). This 3) is flanked by perfect 14-base-pair (bp) direct repeat and full-length, close-to-full-length, this family. LINE 3 contains an approximately 100-bp A-rich right end, number (greater than 400-bp) open reading frames, ca. 200-bp G + C-rich (ca. 60%) cluster near each terminus. Comparison with about one-half another member, which we also present, as well restriction enzyme analysis genomic copies family, indicates that in length overall structure quite typical 40,000 so other members would account for much 10% genome. Therefore, relatively homogeneous, contrasts heterogeneous families primates mice. Transcripts corresponding to entire are abundant nuclear RNA liver. The characteristics discussed respect possible function evolution sequences.
