Tīmeklis(a) DNA transposons. Human DNA transposons contain a single ORF flanked by terminal inverted repeats (TIRs) and by 2‐10 bp long target site duplications (TSDs). (b) LTR retrotransposons. Autonomous elements contain an internal coding sequence with two or more open reading frames. TīmeklisDemonstration of repetitive DNA. DNA from M. tuberculosis strain T2 was digested with endonuclease BamUl and aliquots con-taining 1.45 pg and 145 ng were run on an 0.8 96 agarose gel (20 x 25 cm). The lane containing 1.45 pg of DNA was transferred to a nylon membrane (GeneScreen Plus; NEN-Du Pont, Boston) using the alkaline …
