Nitrogen is a key element in the formation of what, which are substances necessary to living organism?

1 Answer

Answer:

Nitrogen is a key element in both the formation of proteins and the DNA and RNA necessary for life.

Explanation:

Proteins are made of amino acids, which have both a nitrogen group #(NH_2#) and an acid group #(CO_2H)#. Without nitrogen, amino acids and proteins cannot be formed. Proteins are essential for life.

DNA and RNA are made of nucleic bases. These bases contain nitrogen. Without nitrogen, the genetic code needed for life could not be written.
