in selecting recombinant baceria cell ar chosen that are ressutabt to a specific anitbodic how are the bactreia made resistant.

The vector, that is, the bacterium is encoded by the antibiotic resistance gene.

Explanation:

A recombinant organism is the organism that its genetic makeup has been altered, this means, the organism contains different combination of alleles, that can't be found in either of the parents. This is usually done by deliberately introducing new genetic materials or elements.

The offspring produced by these altered organisms also possess the new genetic material that was initially introduced to the altered organisms.

Bacteria have been the most desired organism for this act, because they are easy to grow and nurture.
