Remobilization of Minos in the Ciona genome. (a) Remobilization from a tandem array. (b) An example of enhancer trap lines created using remobilization technique. Green fluorescent protein is expressed in the pharyngeal gill. Bar = 100 μm. (c) Remobilization of Minos from a single inserted site. (d) Excision of single Minos insertion in the somatic cells. The polymerase chain reaction bands show Minos excision from the genome (arrowhead). M, marker lane.
