Linha 44 : ==Vector biologic en [[engenh genetic]]== En [[biologia ~~molecular~~moleculara]] e en [[engenh genetic]], los vectors son de moleculas d'ADN que permetan la propagacion de sequéncias d'interès. S'agís de moleculas d'ADN chimèras coma las [[plasmida]]s o los [[cromosòma artificial bacterian\|cromosòmas artificials bacterians]], contenant una [[origina de replicacion]] e mai d'un [[marcador genetic\|marcadors genetics]]. L'origina de replicacion permet de mantenir lo vector dins la cellula cibla amb las generacions. <!--There is a possibility for confusion between the use of "vector" in gene therapy and its use in molecular biology more generally. Some transformation technologies, such as [[lipofectamine]], enable the direct delivery of a DNA construct as therapy in a [[Biological tissue\|tissue]]. In such a situation, a plasmid vector may be regarded as serving as its own gene-therapy vector. When a speaker calls it "a vector," they may be referring to either of its vector aspects or often both.-->
