Which Genes are Responsible for Nitrogen Fixation

Question

Which genes are responsible for nitrogen fixation?
A)nod genes
B)nif genes
C)fix genes
D)luteolin genes
E)leghemoglobin genes

Accepted Answer

The nif genes are responsible for nitrogen fixation in bacteria. These genes code for the enzymes that are involved in the conversion of atmospheric nitrogen to ammonia, which can then be used by the plant. The nod genes are involved in the formation of root nodules and the establishment of the symbiotic relationship between the plant and the bacteria. The fix genes are involved in the regulation of nitrogen fixation in bacteria. Luteolin genes and leghemoglobin genes are not involved in nitrogen fixation.
