Direct repeats are a type of genetic sequence that consists of two or more repeats of a specific sequence.
Direct repeats are nucleotide sequences present in multiple copies in the genome. There are several types of repeated sequences. Interspersed (or dispersed) DNA repeats (interspersed repetitive sequences) are copies of transposable elements interspersed throughout the genome. Flanking (or terminal) repeats (terminal repeat sequences) are sequences that are repeated on both ends of a sequence, for example, the Long terminal repeats (LTRs) on retroviruses. Direct terminal repeats are in the same direction and inverted terminal repeats are opposite to each other in direction. Tandem repeats (tandem repeat sequences) are repeated copies which lie adjacent to each other. These can also be direct or inverted repeats. The ribosomal RNA and transfer RNA genes belong to the class of middle repetitive DNA.

Famous quotes containing the words repeat and/or direct:
“In 1872 I received a request like this and I did register and vote, for which I was arrested, convicted and fined $100. Excuse me if I decline to repeat the experience.”
—Susan B. Anthony (18201906)
“A temple, you know, was anciently an open place without a roof, whose walls served merely to shut out the world and direct the mind toward heaven; but a modern meeting-house shuts out the heavens, while it crowds the world into still closer quarters.”
—Henry David Thoreau (18171862)
