WebIn a typical cloning experiment, researchers first insert a piece of DNA, such as a gene, into a circular piece of DNA called a plasmid. This step uses restriction enzymes and DNA ligase and is called a ligation. After a ligation, the next step is to transfer the DNA into bacteria in a process called transformation. WebShuttle vectors A shuttle vector is a vector that can propagate in two different host species, hence, inserted DNA can be tested or manipulated in two different cell types. BAC vectors BAC vectors are plasmids constructed with the replication origin of E. coli F factor, and so can be maintained in a single copy per cell.
