Scope note: Secuencias de ADN o ARN que aparecen en múltiples copias. Existen diversos tipos: SECUENCIAS REPETITIVAS ENTREMEZCLADAS, que son copias de elementos invertibles (ELEMENTOS TRASPONIBLES DE ADN o RETROELEMENTOS) dispersos a lo largo del genoma. Las SECUENCIAS REPETIDAS TERMINALES flanquean ambos extremos de otra secuencia, por ejemplo, las repeticiones del terminal largo (LTRs) en los RETROVIRUS. Las variaciones pueden ser repeticiones directas, es decir aquellas que aparecen en la misma dirección, o repeticiones invertidas, las que adoptan direcciones opuestas a las primeras. Las SECUENCIAS REPETIDAS EN TÁNDEM son copias que se agrupan unas junto a otras, directas o invertidas (SECUENCIAS DE REPETICIÓN INVERTIDAS).

Scope note: Sequences of DNA or RNA that occur in multiple copies. There are several types: INTERSPERSED REPETITIVE SEQUENCES are copies of transposable elements (DNA TRANSPOSABLE ELEMENTS or RETROELEMENTS) dispersed throughout the genome. TERMINAL REPEAT SEQUENCES flank both ends of another sequence, for example, the long terminal repeats (LTRs) on RETROVIRUSES. Variations may be direct repeats, those occurring in the same direction, or inverted repeats, those opposite to each other in direction. TANDEM REPEAT SEQUENCES are copies which lie adjacent to each other, direct or inverted (INVERTED REPEAT SEQUENCES).
