Due to this, however, the strain cannot be used with subcloning plasmids containing the TetR gene for selection. The addition of Mg2+ (5 mM) to media is reported to improve the yield of bacteriophage M13 cultures infected at low multiplicity. For some restriction endonuclease mapping experiments, the sum of the fragments of some multiple digestions is less than the total length of the starting DNA because the fortuitous locations of some sites produce fragments of the same size. The E. coli strain XL1-Blue was selected as a model because the Tn10 transposon containing the tetracycline-resistance gene tetA is located in its genome 24. On the right side as marked from lane 8-14 it shows endonuclease digestions and electrophoretic separation of fragments of the plasmid pMB.

For the PstI enzyme, based on the result that has been obtained, PstI has one site when digest pMA plasmid and produced only one fragment, which indicates that it has only one restriction site on the pMA plasmid. After the double digest and based on the data, the following similarities and differences between pMA and pMB plasmid have been observed: First, the length, based on the restriction maps obtained from the gel electrophoresis (Table 3, Fig 3) pMA, is shorter than pMB (Fig 5) since pMA is about 3.6-kb whilst pMB is about 5.05-kb.
