Tandem repeat

This is a term from, which describes a pattern that helps determine an individual's inherited traits.

Tandem repeats and s in occur when a pattern of two or more nucleotides is repeated and the repetitions are directly adjacent to each other. An example would be:
 * ATTCGATTCGATTCG

in which the sequence ATTCG is repeated three times.

Tandem repeats can be very useful in determining parentage. s are used for certain s.

is examined from  within the chromosomal DNA. is another way of saying special regions of the. (or PCR) is performed on the minisatellite areas. The PCR must be performed on each organism being tested. The amplified material is then run through. By checking the percentage of bands that match, parentage is determined.

In the field of, tandem repeats in strings (e.g. DNA sequences) can be efficiently detected using or.
