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?
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.
Biology question.. transformed bacteria?
So, what do you think? You have everything you need to answer the question in the question. Do you know what transformed means? For bacteria, that means that you have transfered DNA into the bacteria. So, if the plasmid contains the gene needed for resistance to penicillin, then transformed bacteria will survive. In Answer B, the transformed bacteria die. That can't be right, correct? So, the answer is B.
