Recombinant DNA bearing ampicillin resistance gene is passed in E. coli. The latter are spread on agar plates containing ampicillin. Then

If a recombinant DNA bearing gene for ampicillin resistance if transferred into E.Coli cells and the host cells are spread on agar plates containing ampicillin, then:

If a recombinant DNA bearing gene for resistance to antibiotic ampicillin is transferred to E.coli cells, the host cells become transformed into ampicillin resistant cells. If such bacteria are transferred on agar plates containing ampicillin, only transformants will grown and the untransformed recipient cells will die. The ampicillin resistant gene in this case is called as

Read the following statements and select the incorrect ones. (i) When the transformed cells on agar plates containing ampicillin are spread, both transformed and untransformed cells with grow. (ii) Restriction enzymes are used in isolation and separation of DNA from other macromolecules. (iii) Downstream processing is one of the steps of rDNA technology. (iv) Disarmed pathogen vectors are also used in transfer of rDNA into the host.

Assertion: The genes encoding resistance to antibiotices are considered as useful selectable markers for E.coli Reason :The normal E.coli does not carry resistance against any of the antibiotics

Assertion (A): The cell division in a plant cell is called an astral division. Reason (R ): Cytokinesis in plant cell takes place by the formation of cell plate.

Some foreign DNA fragment is attached to Cla I site of pB322. This recombinant vector is used to transit Escherichia coli host cells. The cell subjected to transformation are plated on two different media-one containing ampicillin and the other containing tetracycline. THe transformed cells containing the recombinant vector
