Inverted repeats
A DNA or RNA sequence where the sequence of nucleotides along one a strand of DNA is repeated in the opposite physical direction along the other strand; inverted repeats are commonly separated by a tract of non-repeated DNA.
2. Inverted Repeats
In these cases, two different segments of the double helix read the same but in opposite directions.

The structure is two inverted repeats separating one small single copy and one large single copy. This structure is very similar in most plants, the size varies between 120 and 160 kb.
In addition, long inverted repeats flank both ends of the origin, and are thought to be important in the initiation process and may serve a function similar to the DnaA boxes in the eubacteria.
Long terminal repeats have inverted repeats, that is, sequences close to either end are identical when read in opposite directions.
They constist of 800 to 2000 base pairs and carry inverted repeats at their ends. The central part consists of reading frames and codes for transposases responsible for transposition.

The transposase gene is flanked on either side by fifteen to twenty-five base pairs, arranged as "inverted repeats." A composite transposon is composed of any gene sandwiched between two IS sequences; this entire unit will move.
