Editing Expression vector (section)

===Other Elements===
The expression vector is [[transformation (genetics)|transformed]] or [[Transfection|transfected]] into the host cell for protein synthesis. Some expression vectors may have elements for transformation or the insertion of DNA into the host chromosome, for example the [[agrobacterium|''vir'' genes]] for [[Plant transformation vector|plant transformation]], and [[integrase]] sites for chromosomal integration .

Some vectors may include targeting sequence that may target the expressed protein to a specific location such as the [[periplasmic space]] of bacteria.
