Tandem repeat sequence

Tandem repeat sequences Multiple copies of the same base sequence on a chromosome; used as a marker in physical mapping.

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.
