Answer:
The correct option is : cells containing empty plasmid vectors
Explanation:
The blue-white screen is a technique which involves the rapid identification of the recombinant bacteria in a vector-based molecular cloning experiment. In this method, a DNA ligated vector is inserted in a host cell which is viable for transformation and grown in presence of X-gal.
The cells that are transformed with the vectors having the recombinant DNA produce the white colonies. Whereas, the cells transformed with empty vector i.e. the non-recombinant plasmids, produce the blue colonies.
Negative feedback systems are responses in your body that happen in order to maintain homeostasis and balance within a system. One example of negative feedback system is thermoregulation. If we did`nt have that, the temperature of our organisms would change drastically and it could cause bad consequences for our health and body functioning. The correct answer is letter A: Negative feedback systems allow humans to regulate ans stabilize their systems.
