Which gene is used in nitrogen fixation?

Nitrogen fixation:

1. Nitrogen-fixing is the act of removing nitrogen from the atmosphere's molecular form (N₂) and converting it into nitrogen compounds beneficial to other biological processes.
2. Fixation may be brought about by industrial, biological, or atmospheric (lightning) activities.
3. A gene is the primary structural and functional element of heredity.
4. DNA is the component of genes.
5. The nifHDK genes are in charge of producing the proteins that assist plants in converting atmospheric nitrogen into a form that can be utilized by them.
6. The genes are present in both cyanobacteria and bacteria that fix nitrogen.
7. Enzymatic conversion of atmospheric nitrogen dioxide to ammonium is the method by which bacteria fix nitrogen.
8. The nitrogenase enzyme is encoded by the nifHDK gene.
9. The nif genes code for proteins involved in the conversion of atmospheric nitrogen into a form of nitrogen that is accessible to plants.
