What is A monomer nucleic acid?
Nucleotides are monomers of nucleic acids, DNA and RNA. A nucleotide is made up of a nitrogenous base (adenine, thymine, guanine, cytosine, or uracil), a phosphate group (PO43−), and a 5-carbon sugar.
Are nucleotides monomers of proteins?
Each class of macromolecule is made up of different types of monomers. Nucleic acid monomers are called nucleotides; protein monomers are called amino acids; lipid monomers are called fatty acids; and carbohydrate monomers are called monosaccharides (MAH-nuh-SA-kuh-riyd).
Are nucleotides monomers of RNA?
Deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) are polymers composed of monomers called nucleotides.
What are nucleotides made of?
A molecule consisting of a nitrogen-containing base (adenine, guanine, thymine, or cytosine in DNA; adenine, guanine, uracil, or cytosine in RNA), a phosphate group, and a sugar (deoxyribose in DNA; ribose in RNA).
What are the monomers called?
There are four main types of monomer, including sugars, amino acids, fatty acids, and nucleotides. Each of these monomer types play important roles in the existence and development of life, and each one can be synthesized abiotically.
What is the monomer of proteins?
amino acids
For example, proteins are composed of monomers called amino acids. They are linked together to form a polypeptide chain, which folds into a three dimensional (3D) structure to constitute a functional protein (Figure 1).
What are monomers made of?
All monomers have the capacity to form chemical bonds to at least two other monomer molecules. Polymers are a class of synthetic substances composed of multiples of simpler units called monomers.

Monomers and Polymers.
| Bio-Polymer | Type | Monomer(s) |
|---|---|---|
| Proteins | heteropolymer | amino acid units |
| Polynucleotides | heteropolymer | nucleotide units |
Are nucleotides proteins?
4 Nucleotides. Nucleotides are low-molecular-weight compounds comprising a nitrogenous base, a sugar moiety and one to three phosphate groups and belonging to the non-protein nitrogen fraction of milk.
What are the monomers of DNA and RNA?
Nucleotides
- DNA and RNA are polymers (in the case of DNA, often very long polymers), and are made up of monomers known as nucleotides. …
- Each nucleotide in DNA contains one of four possible nitrogenous bases: adenine (A), guanine (G) cytosine (C), and thymine (T).
What is a monomer of RNA?
RNA monomers are also nucleotides. Unlike DNA, RNA in biological cells is predominantly a single-stranded molecule. While DNA contains deoxyribose, RNA contains ribose, characterised by the presence of the 2′-hydroxyl group on the pentose ring (Figure 5).
What are the monomers of DNA and RNA quizlet?
Nucleotides are the building blocks (monomers) of nucleic acids, DNA and RNA.
Is a nucleic acid DNA or RNA?
The two main classes of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). DNA is the master blueprint for life and constitutes the genetic material in all free-living organisms and most viruses.
Where are nucleotides made?
the liver
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. Nucleotides are obtained in the diet and are also synthesized from common nutrients by the liver.
What are the 3 parts of a nucleotide?
Three Parts of Nucleotide
- Sugar.
- Nitrogenous Base.
- Phosphate Group.
Where do nucleotides come from?
Nucleotides are either synthesized from small molecules and amino acids, or they are acquired via salvage pathways from preformed host-derived nucleobases and nucleosides.
What are the 4 types of monomers?
Four big monomers are found: amino acids, nucleotides, monosaccharides, and fatty acids.
What does monomer mean?
monomer, a molecule of any of a class of compounds, mostly organic, that can react with other molecules to form very large molecules, or polymers. The essential feature of a monomer is polyfunctionality, the capacity to form chemical bonds to at least two other monomer molecules.
Is DNA a monomer or polymer?
And even our DNA is a polymer—it’s made of monomers called nucleotides.
What is the monomer of lipids?
Lipids – polymers called diglycerides, triglycerides; monomers are glycerol and fatty acids.
What is the monomer of fats?
Monomers of Fats
The base monomer for fats is the alcohol glycerol, which contains three carbons with hydroxyl groups combined with fatty acids. Fats yield twice as much energy as the simple sugar, glucose. For this reason fats serve as a kind of energy storage for animals.
