What is special about nitrogen and what is its main function in the atmosphere?

Nitrogen is special in that it makes part of the nucleic acids namely DNA and RNA without which there can be no continuity of life  on earth.

Nitrogen is essential to all living systems. About  78 percent of earth's atmosphere is made up of nitrogen gas.

The function of nitrogen in the atmosphere is that forms part of the nitrogen cycle which is essential to life on earth.

During electrical storms, large amounts of nitrogen in the air are oxidized and united with water to form an acid that falls to earth in rainfall and deposits nitrates in the soil.

Plants take up nitrates, essential to plant growth and development,  and convert them to plant protein. Animals consume the plants as food and so life is sustained.

the types of mutations include: missense mutation: this type of mutation is a change in one dna base pair that results in the substitution of one amino acid for another in the protein made by a gene. nonsense mutation: a nonsense mutation is also a change in one dna base pair.

explanation:

he movement of air through earth's or any planet's atmosphere is called wind, and the main cause of earth's winds is uneven heating by the sun. this uneven heating causes changes of atmospheric pressure, and winds blow from regions with high pressure to those with low pressure.

i hope this : )
