See also: vector (4). shuttle vector A DNA plasmid with both bacterial and eukaryotic replicative machinery, which allows it to “promiscuously” propagate within bacteria and yeasts. Recombinant DNA in shuttle vectors can be amplified in bacteria and expressed in eukaryotes.shuttle vectorA short DNA segment, such as may be found in a bacteriophage or a plasmid, that carries DNA between organisms of two different species.See also: vectorshuttle vector a VECTOR (2) that is capable of replicating (see REPLICATION in more than one HOST, for example ESCHERICHIA COLI and YEAST. |
