No change

reason being,

when A piece of foreign DNA was inserted into a plasmid with an antibiotic resistance gene and lactose Z gene. The plasmid DNA was cut with a restriction enzyme, which splits the lactose Z gene and opens the circle. The foreign DNA was next inserted into the open restriction site of the plasmid. In producing antibiotic resistant cloning plasmid, the ColEl plasmids of E. coli have been modified for use as cloning vectors. The original colicin genes have been deleted so that the bacteria carrying these plasmids no longer produce these anti­bacterial toxins. In addition, a gene for antibiotic resistance has been added. This provides an easily identifiable phenotype to the bacteria that carry the altered plasmid. Vectors are often designed to be selected by antibiotic resistance. $\large\rm$
