Preferred Label : repetitive sequences, nucleic acid;
MeSH definition : 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).;
MeSH synonym : nucleic acid repetitive sequences;
