Repeat sequences

Synonym(s)

The length of a nucleotide sequence that is repeated in a tandem cluster.: Definition from: Office of Rare Diseases at the National Institutes of Health
Multiple copies of the same base sequence on a chromosome; used as markers in physical mapping.: Definition from: Human Genome Project Information at the U.S. Department of Energy
A tandem repeat is a sequence of two or more DNA base pairs that is repeated in such a way that the repeats lie adjacent to each other on the chromosome. Tandem repeats are generally associated with non-coding DNA. In some instances, the number of times the DNA sequence is repeated is variable. Such variable tandem repeats are used in DNA fingerprinting procedures.: Definition from: Talking Glossary of Genetic Terms from the National Human Genome Research Institute
