long terminal repeats

long terminal repeats
(LTR) identical DNA sequences occurring at each end of an integrated retrovirus and essential for integration of the molecule into host DNA; each is several hundred nucleotides long and contains a short, inverted, repeated sequence at each of its own ends. Many also contain elements regulating the expression of the DNA they surround.
