Nucleotides are building blocks of nucleic acids which are important for the existence of life.

Explanation:

A cell which is a basic unit of life, if doesn't possess nucleotides then it can no more remain a cell.
The nucleotides present in #"DNA"# are deoxyribonucleotides while in #"RNA"# these are ribonucleotides.

The nucleotides are present in cell's genetic material i.e #"DNA# & also in #"RNA"# which act as a sort of messenger that conveys message of #"DNA# to ribosomes. #"DNA# has portions containing sepcific sequence of these nucleotides. These sections are called genes. This specific sequence of nucleotides on each gene is transcribed into #mRNA#"(made up of nucleotides) and translated in order to form proteins. These proteins are vital for proper body functioning.

Besides, some nucleotides also serve as co-enzymes and thus help to speed up several biochemical reaction taking place in our bodies.
Most common examples are flavin dinucleotide#(FAD)# and Nicotine dinucleotide#(NAD)#.

So, we can say: No nucleotides #to# No life.
