Assertion: GM food which is prepared from GM crops may be more nutritous and good for health than its natural variant
Reason :Bacteria present in the alimentary canal of human could take up the antibiotic resistance gene than is present in GM food. The bacteria would then become resistant to concerned antibiotic

A

If both the assertion and the reason are true and the reason is a correct explanation of the assertion

B

If both the assertion and reason are true but the reason is not a correct explanation of the assertion

C

If the assertion is true but the reason is false

D

If both the assertion and reason are false

Text Solution

Verified by Experts

The correct Answer is:
B
GM food contains the enzyme produced by the antibiotic resistance gene that was during gene transfer by genetic engineering. It also contains the antibiotic resistance gene itself. The enzyme produced by antibiotic resistance gene could cause allergies since it is a foreign gene.
The bacteria residing in the alimentary canal of the humans could take up the antibiotic resistance gene from GM food. These bacteria could develop resistance to the specific antibiotic and could produce difficulties in controlling their population.

What could be the possible harm of using antibiotic resistant gene as a selectable marker in plasmid, used for gene transfer in production of GM food? (A) GM food contains the enzyme produced by the antibiotic resistance gene that was used during gene tranfer in genetic engineering. This could cause allergies since it is a foreign protein. (B) The bacteria present in the alimentary canal of the humans could take up the antibiotic resistance gene present in GM food. (C) The bacteria in the human alimentary canal would then become resistant to the concerned antibiotic. (D) The transgene may be transferred through pollen to their wild relattves and make weeds more persistant and damaging.

Question Stimulus DIRECTIONS: Read the following passage carefully and answer the following Questions. Infections in the roots of teeth are hell to treat. The tooth needs to be drilled into, right down to the bottom of the nerve carrying canal that runs through the root. The infected material must then be cleaned out completely and the drilled section filled in. Although, the procedure is routine, it is common for some of the bacteria to survive it and therefore for infections to re­emerge shortly after treatment. The surviving bacteria are often gathered in the form of what is known as a biofilm. Bacteria in such a film are embedded in a polymer matrix, which makes them harder to kill than isolated individuals. High temperatures can destroy biofilms, as can some chemicals, but neither approach is safe to use inside the delicate interior of a human tooth. However, Chunqi Jiang, a physicist at the University of Southern California, Los Angeles, and her colleagues have come up with a possible alternative: a dental plasma torch. Plasmas are gases in which the molecules have been stripped of some or all of their electrons, to create positive ions. One way to do this is to heat the gas up. Conventional plasma torches employ such hot plasma to cut metal. But cold plasmas can be made using high electrical voltages. Bacteria in biofilms are also more resistant to antibiotics than their isolated confreres, so the new device could have other medical applications. Wound infections, for example, often form biofilms. If they cannot be treated successfully, the result may be gangrene. And if Dr. Jiang’s version of St. Elmo’s fire can deal with that problem, the saint may become patron of a lot more people than just sailors. Why does the writer say ‘Infections in the roots of teeth are hell to treat’?
