Solution

The correct option is D has a competitive advantage when grown in the media that contains tetracycline.
Plasmids are extrachromosomal DNA that are present in bacteria offering them drug resistance. So the bacterial cells that have the plasmid will be more advantageous in a media with tetracycline.
So the correct answer is "has a competitive advantage when grown in the media that contains tetracycline".

It was observed that all the positive clones (containing the DNA fragment of interest) grew on medium with kanamycin but not on media containing spectinomycin. Colonies, which grew on media with both antibiotics, did not contain the fragment of interest. In the absence of any other confounding factors, the statement(s) which could independently explain these observations is/are

Q. A piece of foreign DNA was inserted into a plasmid with an antibiotic resistance gene and lactose Z gene. The plasmid DNA was cut with a restriction enzyme, which splits the lactose Z gene and opens the circle. The foreign DNA was next inserted into the open restriction site of the plasmid. When the recombinant plasmid was introduced into bacterial cells and grown in the presence of antibiotic, some of the colonies turned blue in the presence of gene. The blue colonies contained
