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.
