Monomers of nucleic acids are compound components.
This article contains information about the elements of all nucleic acids, namely its monomers. Here you will find information about their structure, diversity of existing species, etc.
Nucleic acid - what is it
The most important component of any plant, animal, bacterial, and even viral cell is nucleic acid, which is responsible for transmitting, reproducing and storing information of hereditary type. Biopolymer compounds - nucleic acids - are created by encoding nucleotides. Ribonucleic acid (RNA) and deoxyribonucleic acid (DNA) are nucleic acids. Nucleotide monomers of nucleic acids are 5 types, of which 3 are suitable for both deoxy and ribonucleic acids, and the remaining nucleotides are different.
A variety of nucleic acids
DNA and RNA are representatives of nucleic acid class,however, the latter ribonucleic acid, according to the functions for which it is intended in a cell, may have different names, for example: transport ribonucleic to-that (tRNA) or informational ribonucleic to-that (mRNA). However, this item does not affect the features of the structure itself. What is a nucleic acid monomer? The answer to this question will be the enumeration of elements: ribose and deoxyribose (types of sugars), HPO3 acid, or rather, its residues and in the bases of thymine (uracil) and adenine, guanine and cytosine.
Nucleic acid monomers are three constituents, as mentioned earlier, which is a monosaccharide; those with heterocyclic properties are nitrogenous bases and the acidic residue HPO3. The constituent types of monomers of nucleic acids are the purine derivatives of adenine (A) and guanine (H) substances and components of pyrimidine nature: cytosines (C), thymine (T) and uracil (U). It is also worth knowing about the existence of atypical bases, whose representatives are pseudouridines and dihydrouridines.
The nucleic acid monomers are responsible for the vital functions of the substance, inherent in both prokaryotic and eukaryotic organisms.Nucleic acids are classified according to the monosaccharide of which the acid itself is represented. Ribose to-you are represented by ribose, and nucleic to-you, represented by deoxyribose, are called deoxyribose. The dominant difference between the chains of RNA and DNA lies in the presence of either thymine or uracil in the chains of the molecule. DNA carries pyrimidine thymine, and RNA - uracil. These two nucleotides are replaced in these acids and become complementary to adenine.
Nucleic acid monomers are compounds based on a chemical bond — 3.5-phosphodiester, which forms linear structures, and its purpose is to bind pentose in the nucleotide. This design of nucleic acids allows one to form a free 3-OH group on one chain end and to position the 5-OH group on the opposite end of the chain.
RNA and DNA are universal and unique to all organisms. This is due to their ability to transfer and preserve a variety of information that carries genetic heredity. Virtually every living organism carries both acids simultaneously.based on both the ribose monosaccharide and deoxyribose, and only viruses — representatives of the non-cellular life form — contain only one form of nucleic acid.
