Plasmid pBR322 has a PstI restriction enzyme site within gene ampR that confers ampicillin resistance. If this enzyme is used for inserting a gene for -galactoside production and the recombinant plasmid is inserted in an E.coli strain,
| 1. | it will lead to the lysis of host cells. |
| 2. | it will be able to produce a novel protein with dual abilities. |
| 3. | it will not be able to confer ampicillin resistance to the host cell. |
| 4. | the transformed cells will have the ability to resist ampicillin as well as produce β -galactoside. |
