What is the relationship between the nucleotides, nucleic acids, and DNA? | Socratic
Nucleic acids contain genetic information and enable synthesis of proteins. Each connection between nucleotides is a covalent bond, so the nucleic acids. Nucleic acids include DNA and RNA. These molecules are composed of long strands of nucleotides. Nucleotides are composed of a. derivatives are the most common free nucleotides, because ATP is used in the Synthesis of nucleic acids (and especially synthesis of DNA) requires synthesis.
They serve as an energy source and signal transducer. Nucleic acids are involved in gene expression as well as the storage of genetic information. Conclusion Nucleotides are the monomers of nucleic acids. Nucleotides consist of a nitrogenous base and a phosphate group attached to a pentose sugar. Two types of nucleic acids can be found depending on the type of the pentose sugar in the nucleic acid backbone. When the pentose sugar is ribose, the forming nucleic acid is RNA. On the other hand, when the pentose sugar is deoxyribose, the resultant nucleic acid is DNA.
DNA is the most widely used nucleic acid in storing of genetic information in the cell. According to the nucleotide sequence on the DNA molecule, the genetic information can be stored in written form.
RNA is involved in the process of gene expression. Therefore, the main difference between nucleotide and nucleic acid is in their relationship between monomers and polymers of each other. National Library of Medicine, 01 Jan.
Relation among Nucleic Acids, Nucleotides and Nucleosides
Nucleotides are added based on complementary base-pairing discussed below. RNA is a long single chain of nucleotides. Each sugar is ribose. The nitrogenous bases are Adenine, Cytosine, Guanine, and Uracil. The process of RNA synthesis is called transcription.

To see an enlarged version of this figure, click here. DNA is a pair of long chains of nucleotides. Each sugar is deoxyribose. The nitrogenous bases are Adenine, Cytosine, Guanine, and Thymine.
The process of DNA synthesis is called replication. At left is an "unfolded" view of a double-stranded DNA molecule, showing the two chains of nucleotides, connected in the center by a series of hydrogen bonds between nitrogenous bases. At right, a schematic illustration showing the arrangement of the two strands in the double-helix configuration. The "backbone" on the outside is the sugar-phosphate chain, and the nitrogenous bases form the bridges across the middle.

The two strands of DNA backbone are visible as red and grey balls; the nitrogenous bases are the blue and grey regions in the center of the double helix. Nitrogenous bases can form hydrogen bonds.
What is the relationship between the nucleotides, nucleic acids, and DNA?
These are defined as polynucleotides composed of repeating units ribonucleotides in RNA or deoxyribonucleotides in DNA. The presence of three esterifiable-OH groups in the ribose portion or two in the deoxyribose portion gives rise to several possible phosphoesters. Nucleotides are building blocks of large molecules. They serve three crucial functions in cells. Some are energy carriers, other are co-enzymes and still others are carriers of hereditary information genetic code.
Structurally, a nucleotide can be regarded as a phosphoester of a nucleoside. In turn, a nucleoside is a N-glycoside in which the sugar component is ribose or deoxyribose and aglucon is a pyrimidine or purine base.
