In Drosophila, they are maintained by non-LTR retrotransposons, and the Hayflick limit is the inability to maintain them in somatic cells. In vertebrates, they form unusual GG pairings while an enzyme catalyzes translocation and hybridization after adding dNTPs specified by an RNA template. Usually rich in guanine, they have 3' [three prime] ends extending 12 to 16 nucleotides beyond the complementary cytosine-rich strand. For 10 points, name these TTAGGG sequence repeats that are maintained in germline and tumor cells, making them immortal.
