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.
In biological systems, genetic information is stored in a chain of nucleotides called a nucleic acid. It produces DNA and RNA, which hold the data required by cells to produce proteins. Codons, which are collections of three nucleotides, are used to retain this data. A nucleic acid is often a big molecule formed of a string, or "polymer," of units referred to as "nucleotides." All life on the planet employs nucleic acids as a medium for storing genetic information; in other words, nucleic acids serve as the hard drives that store the vital "source code" for building cells.
