Show Answer
Answer:
Correct Answer: D
Solution:
[d] The transgene may get transferred through pollen to their wild relatives, which may make those weeds more persistent and damaging.
The transgenic crop themselves may become persistent weeds.
Such crops can also damage the environment in some yet unknown manner.
The enzyme produced by the antibiotic resistance gene could cause allergies, as it is a foreign protein.
The bacteria present in the human alimentary canal could take up the antibiotic-resistance gene from the food and become resistant to that particular antibiotic.
