An inverted repeat (or IR) is a sequence of nucleotides that is the reversed complement of another sequence further downstream.
For example, 5'---GACTGC....GCAGTC---3'. When no nucleotides intervene between the sequence and its downstream complement, it is called a palindrome. Inverted repeats define the boundaries in transposons. Inverted repeats also indicate regions capable of self-complementary base pairing (regions within a single sequence which can base pair with each other).

Famous quotes containing the words inverted and/or repeat:
“Can they never tell
What is dragging them back, and how it will end? Not at night?
Not when the strangers come? Never, throughout
The whole hideous inverted childhood? Well,
We shall find out.”
—Philip Larkin (1922–1986)
“Guilty, guilty, guilty is the chant divorced parents repeat in their heads. This constant reminder remains just below our consciousness. Nevertheless, its presence clouds our judgment, inhibits our actions, and interferes in our relationship with our children. Guilt is a major roadblock to building a new life for yourself and to being an effective parent.”
—Stephanie Marston (20th century)
