According to Purdue University, nucleotides are used to construct nucleic acids, including DNA, tRNA, rRNA and mRNA. Nucleic acids are long polymers of nucleotides that store and transfer information and regulate processes within the cells of all life forms on Earth.Continue Reading
Three units comprise each nucleotide: a sugar, an amine and a phosphate. A nucleic acid polymer is formed when the phosphate and sugar components of adjacent nucleotides bind together to form the backbone of the polymer.
Nucleic acids are:
DNA stores the genetic material of an organism. The sequence of nucleotides along the DNA strands controls the sequence of amino acids added to the proteins as they are synthesized and plays a role in regulating which proteins are produced.
Several types of RNA transfer information within the cell and help regulate cellular processes.
