Suppose a bacterial culture were mixed with recombinant plasmids containing a gene for resistance to penicillin. The bacterial culture was then treated with penicillin. Which of the following statements is NOT true? Question 10 options: a. Those bacteria that contain the plasmid will survive. b. The penicillin will kill the bacteria that were transformed. c. The gene for antibiotic resistance is expressed in the bacteria that survive. d. Those bacteria that are successfully transformed will survive.

The penicillin will kill the bacteria that were transformed is not a true statement.

Explanation:

The bacterial culture is genetically engineered with recombinant plasmids containing genes resistant to penicillin, hence when treated with penicillin, the bacteria will not be killed.

Bacteria develops resistance to chemicals or drugs like antibiotics namely penicillin over the course and becomes resistant to the drug action. The effectiveness of the drug will either be reduced or eliminated and the bacteria gains the ability to survive, reproduce and grow and increase their colony.

Recombinant bacteria will undergo genetic mutation and can develop resistance against antibiotics like penicillin. The recombinant plasmids further provides extra protection and prevents the entry of drugs or chemicals into the bacterial cell.
