Tandem repeat

Tandem repeats occur in DNA when a pattern of nucleotides is repeated. The repeats sit next to each other, in tandem. These are multiple copies of the same base-pair sequence lying end-to-end.^[1]^[2]^[3]^[4]

An example would be: ATTCG ATTCG ATTCG in which the sequence ATTCG is repeated three times.
