Question

The nitrogen-fixing ability can be increased by inoculating _____ gene in the genome of a particular plant.

• A. Bt
• B. Disease resistant
• C. Nif
• D. None of the above

Answer 1

Answer: (C)

Nif

Nif genes are found in nitrogen-fixing organisms and codes for nitrogenase enzyme responsible for Nitrogen fixation. Nif is a Nitrogen fixation gene which occurs in Rhizobium. It fixes an atmospheric nitrogen into a form of nitrogen available to living organisms. Hence, by inoculating Nif gene in the genome of particular plant, the nitrogen fixing ability of plant could be increased.

Thus, the correct answer is option C.
