Every cell contains a DNA "cookbook" that provides directions on how to make and maintain that cell When a cell reproduces, it must duplicate its DNA, providing one copy to the new offspring cell while keeping one copy for itself Wafton and Crick realized that the chemical properties of each kind of base in DNA dictated the base pairings Each base has protruding chemical groups that can best form hydrogen bonds with only one appropriate partner Besides having practical purposes, a shared genetic vocabulary also reminds us of the kinship that connects all life on Earth The process of DNA replication requires the cooperation of more than a dozen enzymes and other proteins

Nucleotides

It is an organic molecule made up of three basic components- a nitrogenous base, phosphate,and pentose sugar. The nucleotides are important for metabolic reactions andthe formation of DNA (deoxyribonucleic acid) and RNA (ribonucleic acid). 

Nucleic Acids

Nucleic acids are essential biomolecules present in prokaryotic and eukaryotic cells and viruses. They carry the genetic information for the synthesis of proteins and cellular replication. The nucleic acids are of two types: deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). The structure of all proteins and ultimately every biomolecule and cellular component is a product of information encoded in the sequence of nucleic acids. Parts of a DNA molecule containing the information needed to synthesize a protein or an RNA are genes. Nucleic acids can store and transmit genetic information from one generation to the next, fundamental to any life form.
