What Is The Use Of Nucleic Acids – Nucleic acid is a biological polymer or biopolymer that is essential to life and contains nitrogenous bases, a 5-carbon sugar (pentose) sugar, and phosphate groups. The two types of nucleic acids are DNA and RNA. They are “nucleic acids” because DNA is found in the nucleus of eukaryotic cells and is chemically acidic. Nucleic acids carry the genetic information of all organisms and direct protein synthesis.

There are three types of DNA and several types of RNA. Here are some examples of these nucleic acids:

What Is The Use Of Nucleic Acids

Thus, DNA and RNA are two classes of nucleic acids that occur in nature. However, scientists also synthesize artificial nucleic acid analogues. Synthetic molecules mainly differ from DNA or RNA by the composition of their backbones.

Nucleic Acids — The Use Of Nucleic Acid Testing In Molecular Diagnostics

Nucleic acid is a polymer consisting of nucleotide monomers linked together. Each nucleotide has three parts:

Each base has a ring structure and is divided by its structure and either a purine or a pyrimidine. The purines are adenine and guanine, while the pyrimidines are cytosine, thymine (in DNA), and uracil (in RNA). Purines and pyrimidines form bonds with each other, where adenine (A) is linked to thymine (T) or uracil (U) and guanine (G) is linked to cytosine (C).

The 5 carbon or pentose sugar is between the nitrogen base and the phosphate group. In DNA, the sugar is 2′-deoxyribose. In RNA, the sugar is ribose. The carbon atoms of sugar are numbered 1′, 2′, 3′, 4′, and 5′. A base attaches to the 1′ carbon of the sugar, while a phosphate attaches to the 5′ carbon.

The phosphate group attaches to the pentose sugar. Together, the sugars and phosphate groups form the backbone of the DNA or RNA helix. While a nucleotide has 1, 2, or 3 phosphate groups, a nucleic acid has only one phosphate group.

Nucleic acids have a helical shape (with some exceptions in RNA). DNA forms a double helix, while most RNA forms a single helix. The phosphate of one nucleotide binds to the OH group on the 3′ carbon of the sugar of the next nucleotide. This linkage is an ester linkage. The process repeats itself, forming a backbone of other phosphate and sugar subunits. The purines and pyrimidines are off the back.

The backbone is “directed” because one end has a free sugar (3′ end), while the other end has a free phosphate group (5′ end). The two strands of the DNA helix are antiparallel, so the 3′ end of one strand passes from the 5′ end of the other strand, with bases connected between them. By convention, chemists read the code of nucleic acid starting with the 5′ end. So, the genetic code of guanine, thymine, adenine, cytosine is 5′-dG-dT-dA-dC-3′ or simply GTAC.

Nucleic acids are naturally occurring chemical compounds that serve as the primary information carriers in cells. They play an especially important role in regulating protein synthesis. The two main classes of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).

Nucleic acids are long chain-like molecules made up of a series of similar building blocks called nucleotides. Each nucleotide has a nitrogen-containing aromatic base attached to a pentose (five carbon) sugar, which is in turn attached to a phosphate group.

Each nucleic acid contains four of the five possible nitrogenous bases: adenine (A), guanine (G), cytosine (C), thymine (T), anduracil (U). A and G are classified aspurine, and C, T, and U are called pyrimidine. All nucleic acids have the bases A, C, and G; T, however, is found only in DNA, while U is found in RNA.

Nucleic acid, a naturally occurring chemical compound capable of breaking down to form phosphoric acid, sugars, and a mixture of organic bases (purines and pyrimidines). Nucleic acids are the materials that carry the basic information of the cell, and by directing the process of protein synthesis, they determine the inherited characteristics of all living things. The two main classes of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). DNA is the master blueprint for life and is the genetic material in all living organisms and many proteins. RNA is the genetic material of some proteins, but it is also found in all living cells, where it plays an important role in certain processes such as making proteins.

This article covers the chemistry of nucleic acids, describing the structures and properties that allow them to function as transmitters of genetic information. For a discussion of the genetic code,

Nucleic acids are polynucleotides—that is, long chain-like molecules that contain a series of similar building blocks called nucleotides. Each nucleotide has a nitrogen-containing aromatic base attached to a pentose sugar (five carbons), which is then attached to a phosphate group. Each nucleic acid contains four of the five possible nitrogen-containing bases: adenine (A), guanine (G), cytosine (C), thymine (T), and uracil (U). A and G are classified as purines, and C, T, and U are collectively called pyrimidines. All nucleic acids have the bases A, C, and G; T, however, is found only in DNA, while U is found in RNA. The pentose sugar in DNA (2′-deoxyribose) differs from the sugar in RNA (ribose) by the lack of a hydroxyl group (-OH) on the 2′ carbon of the sugar ring. Without an attached phosphate group, a sugar attached to one of the bases is known as a nucleoside. A phosphate group connects successive sugar residues by linking the 5′-hydroxyl group on one sugar to the 3′-hydroxyl group of the next sugar in the chain. These nucleoside linkages are called phosphodiester bonds and are the same in RNA and DNA.

Nucleotides are synthesized from readily available sources in the cell. The ribose phosphate portion of both purine and pyrimidine nucleotides is synthesized from glucose via the pentose phosphate pathway. A six-atom pyrimidine ring is first synthesized and then attached to ribose phosphate. The two rings in purines are produced when attached to ribose phosphate during the assembly of adenine or guanine nucleosides. In both cases the end product is a nucleotide carrying a phosphate attached to the 5′ carbon on the sugar. Finally, a specialized enzyme called a kinase adds two phosphate groups using adenosine triphosphate (ATP) as a phosphate donor to form ribonucleoside triphosphate, the immediate precursor of RNA. For DNA, the 2′-hydroxyl group is removed from ribonucleoside diphosphate to give deoxyribonucleoside diphosphate. The additional phosphate group from ATP is then added by another kinase to form a deoxyribonucleoside triphosphate, immediately forming DNA.

Solution: Experiment 4a Nucleic Acids

During normal cell production, RNA is constantly being made and broken down. Purine and pyrimidine residues are also used by many salvage pathways to make more genetic material. Purine is recorded in the form of the corresponding nucleotide, while pyrimidine is recorded as a nucleoside. Nucleic acids are key macromolecules in the advancement of life. They carry the genetic makeup of the cell and carry the instructions for the functioning of the cell. The two main types of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). DNA is the genetic material found in all living organisms, ranging from single-celled bacteria to multicellular mammals. Another type of nucleic acid, RNA, is mostly involved in protein synthesis. DNA molecules do not leave the nucleus, but instead use the RNA medium to communicate with the rest of the cell. Other types of RNA are also involved in protein synthesis and regulation. We will go into more detail about nucleic acids in a later section.

DNA and RNA are monomers known as nucleotides linked together in a chain with covalent bonds. Each nucleotide is made up of three components: a nitrogenous base, a five carbon sugar, and a phosphate group (Figure 1). The nitrogenous base in a nucleotide is attached to a sugar molecule, which is attached to a phosphate group.

Number 1 Nucleotide consists of three components: a nitrogenous base, a pentose sugar, and one or more phosphate groups.

Nitrogenous bases, the main components of nucleotides, are organic compounds and are named because they contain carbon and nitrogen. They are bases because they have an amino group that has the ability to bind an additional hydrogen, and thus, reduce the hydrogen ion concentration in its environment, making it more basic. Each nucleotide in DNA contains one of four possible nitrogenous bases: adenine (A), guanine (G), cytosine (C), and tamine (T). RNA contains pure uracil (U) instead of thymine. Them
