Is nucleic acid natural or synthetic?
Nucleic acids are naturally occurring chemical compounds that serve as the primary information-carrying molecules in cells. They play an especially important role in directing protein synthesis. The two main classes of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).
Examples of naturally occurring polymers are silk, wool, DNA, cellulose and proteins.
Nucleic acids are polymers of nucleotides joined by covalent (phosphodiester) bonds formed between their sugar and phosphate groups.
Cellulose rayon is not a natural polymer. Rayon is an artificial textile material composed of regenerated and purified cellulose derived from plant sources.
Synthetic genetic polymers, also known as xeno-nucleic acids (XNAs), are chemically modified or synthesized analogues of natural nucleic acids.
Nucleic acids are biopolymers, macromolecules, essential to all known forms of life. They are composed of nucleotides, which are the monomers made of three components: a 5-carbon sugar, a phosphate group and a nitrogenous base.
Natural polymers, also called biopolymers, are naturally occurring materials, formed during the life cycles of green plants, animals, bacteria, and fungi. They are classified mainly into three groups: polysaccharides, polypeptides, and polynucleotides [26–28].
Natural polymers Those polymers which are found in plants and animals are called natural polymers, e.g., starch, cellulose, proteins etc. Synthetic polymers Those polymers which are synthesized with the help of chemicals in industries are called synthetic polymers e.g., polythene, nylon - 6, 6 synthetic rubber etc.
Cellulose, which makes up the cell wall of plants, is another natural polymer. The proteins we eat, and which we're made of, are polymers made up of amino acids. And even our DNA is a polymer—it's made of monomers called nucleotides. The first man-made polymers were actually modified versions of these natural polymers.
A nucleic acid is a polymeric macromolecule made up of repeated units of monomeric 'nucleotides' composed of a nitrogenous heterocyclic base which is either a purine or a pyrimidine, a pentose (five carbon) sugar (either ribose or 2′-deoxyribose), and one to three phosphate groups.
Why are nucleic acids called polymers?
Polymers can be described as chains of repeating monomeric units connected with each other by covalent bonds. In case of nucleic acids, monomers are the nucleotides composed of nitrogenous base, pentose sugar, and phosphate group whereas DNA and RNA are considered as polymer of nucleic acids.
DNA consists of two long polymers (called strands) that run in opposite directions and form the regular geometry of the double helix. The monomers of DNA are called nucleotides.
Proteins are natural polymers.
They can be classified into four main categories: thermoplastics, thermosets, elastomers, and synthetic fibers. They are commonly found in a variety of consumer products. Various main chains and side chains are used to make different synthetic organic polymers.
There are four basic kinds of biological macromolecules: carbohydrates, lipids, proteins, and nucleic acids. These polymers are composed of different monomers and serve different functions.
Nucleotide also has a phosphate group and a nitrogen base in addition to the five carbon sugars. This is why DNA isn't classified as a carbohydrate polymer.
Nucleotides. DNA and RNA are polymers (in the case of DNA, often very long polymers), and are made up of monomers known as nucleotides. When these monomers combine, the resulting chain is called a polynucleotide (poly- = "many").
Nucleotides are organic molecules consisting of a nucleoside and a phosphate. They serve as monomeric units of the nucleic acid polymers – deoxyribonucleic acid (DNA) and ribonucleic acid (RNA), both of which are essential biomolecules within all life-forms on Earth.
Nucleic acids are made of nitrogen-containing bases, phosphate groups, and sugar molecules. Each type of nucleic acid has a distinctive structure and plays a different role in our cells.
Deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) are polymers composed of monomers called nucleotides.
What are nucleic acid are made up of?
Nucleotides comprise adenine(A), guanine(G), cytosine(C) and uracil (U) in RNA. It helps in protein synthesis carrying messenger information from DNA. Based upon their function there are 3 types of RNA :- rRNA, mRNA and tRNA. Thus the nucleic acids are made up of nucleotides.

Some of the examples of synthetic polymers are polyethylene (PE), polystyrene (PS), polyamides (nylon), poly(vinyl chloride) (PVC), synthetic rubber, teflon, epoxy, and several others [10].
Natural bio-based monomers and biopolymers commonly used in biological scaffold production include collagen, fibrin, fibrinogen, platelet-rich plasma, alginate, gelatin, albumin, and hyaluronic acid.
Natural materials come from the natural environment, and have been changed very little. Plastics are an example of a synthetic material. A synthetic material is a material that is obtained from a natural material which has undergone a chemical reaction in a laboratory or factory.
There are three main structure types of natural polymers. Polynucleotides are chains of nucleotides, the build blocks of nucleic acids. DNA and RNA, which control the genetics of living things, are examples of polynucleotides. Polyamides are chains of proteins.
