Dna inverted repeat
WebDNA transposons contain terminal inverted repeats. Which of the following sequences would you expect to see flanking an insertion sequence? 5' - TCCAGGCAC. . . . GTGCCTGGA - 3' Which DNA mutagen results in a transversion mutation? Oxygen radicals Which DNA mutagen results in a frameshift mutation? Acridine orange Many repeat sequences are likely to be non-functional, decaying remnants of Transposable elements, these have been labelled "junk" or "selfish" DNA. Nevertheless, occasionally some repeats may be exapted for other functions. Tandem repeats are repeated sequences which are directly adjacent to each other in the genome. Tandem repeats may vary in the number of nucleotides comprising the repeated sequence, as …

It identifies regions of local alignment of the input sequence and its reverse complement that exceed a threshold score. The alignments may include a proportion of mismatches and gaps, which correspond to bulges in the stem loop.
