12. If you used the PBLU plasmid as a vector to carry a desirable human gene into E. coli recipient cells. The insertion site is inside the B-galactosidase gene on the p-BLU plasmid. After the transformation, you plate the cells on LBA+amp+X-Gal to screen for E. coli cells with the desirable gene. You saw both blue and white colonies on the plate. Which type of colonies carry the desirable human gene? A. White B. Blue C. both D. neither one...

You have isolated a DNA fragment containing a human gene involved in lung cancer and are working inserting it into a standard plasmid vector used in molecular cloning which has a multiple cloning site in the lacZ gene. After cutting the DNA fragment and the vector with the same restriction enzyme and ligating the cut DNA, you transform bacteria with hopefully the recombinant vector. How do you expect to identify bacteria with the recombinant vector? A. Bacteria with the recombinant...

1.A research group is investigating the potential infectious nature of a disease. From ulcerative skin lesions in mice they were able to grow as pure cultures a Gram negative microorganism. They inoculated this microorganism into the skin of healthy mice and reproduced the same ulcerative skin lesions. According to the Koch’s postulated these experimental evidences are sufficient to confirm that the Gram negative microorganism is the causative agent of the studied disease. (T/F) 2. Exotoxins can cause tissue damage during...
