Detailed explanation-1: -The nif genes are responsible for the coding of proteins related and associated with the fixation of atmospheric nitrogen into a form of nitrogen available to plants. These genes are found in nitrogen fixing bacteria and cyanobacteria.

Detailed explanation-2: -The nif genes are genes encoding enzymes involved in the fixation of atmospheric nitrogen into a form of nitrogen available to living organisms.

Detailed explanation-3: -In most bacteria, regulation of nif genes transcription is done by the nitrogen sensitive NifA protein. When there isn’t enough fixed nitrogen available for the organism’s use, NtrC triggers NifA expression, and NifA activates the rest of the nif genes.

Detailed explanation-4: -The nifE, nifN, and nifB encoded proteins play essential role in the assembly and incorporation of Fe and Mo atoms into the nitrogenase subunits.
