a. Wrong - you will not be able to see such bacteria on the plates. The plasmids bear a gene that conferes resistance to a certain antibiotic agent - ampicilin. (Click here to view the plasmid again.) The bacteria are grown on agar plates containing that particular antibiotics. Thus, only bacteria that contain plasmids can survive and be detected.

b. Right -  the plasmids bear a gene that conferes resistance to a certain antibiotic agent - ampicilin (Click here to view the plasmid again). The bacteria are grown on agar plates containing that particular antibiotics. Thus, only bacteria that contain plasmids can survive and be detected. The color of the colonies will tell you a little more about these plasmids.
