Nitrogen is a fundamental element required during the growth and development of any organism.
- Nitrogen is a fundamental chemical element required to synthesize different biomolecules such as nucleic acids (either DNA or RNA) and proteins.
- Amino acids are the bounding blocks of proteins, whereas nucleotides are the building blocks of nucleic acids, and both contain nitrogen.
- All organisms in their growth phase requires nitrogen in order to synthesize these biomolecules (i.e., nucleic acids and proteins).
In conclusion, Nitrogen is a fundamental element required during the growth and development of any organism.
