[中文釋義] 復制區(qū)
[英文釋義] 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 occuring 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.
