![]() ![]() gambiae genome organization could best be described as islands of short-period interspersion repetitious DNA in a sea of long-period ![]() Single Ikirara inverted repeats were also found adjacent to nontransposable element repetitious sequences. Ozymandias, the only LTR retrotransposon found in the clones, is most similar to the Drosophila melanogaster 412 element. Approximately 753 bp is missing from the central portion of the JuanAg reverse transcriptase gene, where an Ikirara inverted repeat is found in its stead. JuanAg is the first anopheline member of the mosquito non-LTR retrotransposon family of Juan elements that previously had included just the culicine elements JuanA and JuanC. Although RT1 and RT2 elements normally have a highly stereotyped insertion preference for sequences within ribosomal genes, Guildenstern is not located in ribosomal sequence. Guildenstern is a member of the RT1 and RT2 non-LTR retrotransposon family. gambiae non-LTR retrotransposable elements. Vash elements, represented twice in our clones, are related to the Q/T1 family of A. One TE is related to the mariner/Tc1 superfamily of class II (DNA-to-DNA) transposons, while four are related to class I (RNA-mediated transposition) elements.Ĭrusoe, the class II element, is most similar to the Caenorhabditis elegans transposon Tc1-like TEs. Characterization of Anopheles gambiae genomic clones containing Ikirara inverted repeats revealed five novel sequences related to known transposable elements (TEs). ![]()
