DNAs,Selfish | 《英文msh词典》DNAs,Selfish | | [入口词] DNAs,Selfish | | [主题词] Repetitive Sequences,Nucleic Acid | | [英文释义] 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. |
