There are four major classes of large biological molecules—carbohydrates, lipids, proteins, and nucleic acids. Carbohydrates are made up of monomers called monosaccharides that contain carbon, oxygen, and hydrogen.

Which biological molecule is a monomer?
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 biological molecule of DNA?
Deoxyribonucleic acid (DNA) is a molecule that contains the biological instructions that make each species unique. DNA, along with the instructions it contains, is passed from adult organisms to their offspring during reproduction.
What are the three biological molecules?
Biomolecules have a wide range of sizes and structures and perform a vast array of functions. The four major types of biomolecules are carbohydrates, lipids, nucleic acids, and proteins.
What is a nucleotide monomer?
The monomers of DNA are called nucleotides. Nucleotides have three components: a base, a sugar (deoxyribose) and a phosphate residue. The four bases are adenine (A), cytosine (C), guanine (G) and thymine (T). The sugar and phosphate create a backbone down either side of the double helix.
What is the monomer of nucleic acids?
Nucleic acids are giant biomolecules made of monomers called nucleotides. Nucleotides have three components: pentose sugar (5-carbon sugar), phosphate group, and nitrogenous base.
What are 4 examples of nucleic acids?
- deoxyribonucleic acid (DNA)
- ribonucleic acid (RNA)
- messenger RNA (mRNA)
- transfer RNA (tRNA)
- ribosomal RNA (rRNA)
What are 4 types of organic molecules?
The four types most important to human structure and function are carbohydrates, lipids, proteins, and nucleotides.
Which of the following are examples of monomers?
What are examples of monomers? Examples of the monomers are glucose, vinyl chloride, amino acids, and ethylene. Every monomer can link up to form a variety of polymers in different ways. For example, in glucose, glycosidic bonds that bind sugar monomers to form polymers such as glycogen, starch, and cellulose.
What is called DNA?
DNA is made up of a double-stranded helix held together by weak hydrogen bonds between purine-pyrimidine nucleotide base pairs: adenine (A) paired with thymine (T), and guanine (G) paired with cytosine (C). Also called deoxyribonucleic acid.
What are biological molecules?
Definition: A biomolecule is a chemical compound found in living organisms. These include chemicals that are composed of mainly carbon, hydrogen, oxygen, nitrogen, sulfur and phosphorus. Biomolecules are the building blocks of life and perform important functions in living organisms.
Is RNA made of nucleotides?
DNA and RNA are polymers comprised of many nucleotides, strung together like beads in a necklace.
What is the name of the monomer for proteins?
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 biological molecules made up of?
Biological macromolecules are organic, meaning that they contain carbon atoms. In addition, they may contain atoms of hydrogen, oxygen, nitrogen, phosphorus, sulfur, and additional minor elements. These molecules are made up of subunits called monomers. Each type of biological molecule is made up of different monomers.
Is nucleic acid a nucleotide?
A nucleic acid is a long molecule made up of smaller molecules called nucleotides. Nucleic acids were discovered in 1868, when twenty-four-year-old Swiss physician Friedrich Miescher isolated a new compound from the nuclei of white blood cells.
Which molecule is a nucleotide?
Nucleotide A nucleotide is the basic building block of nucleic acids (RNA and DNA). A nucleotide consists of a sugar molecule (either ribose in RNA or deoxyribose in DNA) attached to a phosphate group and a nitrogen-containing base. The bases used in DNA are adenine (A), cytosine (C), guanine (G) and thymine (T).
What are examples of nucleotide?
A nucleotide is a monomer that serves as the building blocks for deoxyribonucleic acid (DNA) or ribonucleic acid (RNA). Examples of nucleotides are ribonucleotides or deoxyribonucleotides.
Which of the following nucleic acids are composed of nucleotides?
Nucleic acids, macromolecules made out of units called nucleotides, come in two naturally occurring varieties: deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).
What are the monomers of nucleic acids quizlet?
The monomers of nucleic acids are called nucleotides.
What monomer is amino acids?
Amino Acids: Monomers of Proteins An amino acid is a subunit of protein, a polymer found throughout nature. An amino acid is therefore the monomer of protein. A basic amino acid is made from a glucose molecule with an amine group (NH3), a carboxyl group (COOH), and an R-group (side chain).
What are the 3 parts of nucleotide?
Nucleotides contain three characteristic components: a nitrogenous base, a pentose, and one or more phosphate groups. The nitrogenous bases are derivatives of two parent heterocyclic compounds, purine and pyrimidine. The major pyrimidine bases are cytosine, thymine, and uracil.
What are the 5 nucleic acids?
Strings of nucleotides are bonded to form helical backbones—typically, one for RNA, two for DNA—and assembled into chains of base-pairs selected from the five primary, or canonical, nucleobases, which are: adenine, cytosine, guanine, thymine, and uracil.
What are the types of nucleic acid?
The two main classes of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).
What is DNA and RNA?
DNA is a double-stranded molecule that has a long chain of nucleotides. RNA is a single-stranded molecule which has a shorter chain of nucleotides. Propagation. DNA replicates on its own, it is self-replicating. RNA does not replicate on its own.
What are the 4 major life molecules?
- Each of these exists as a polymer, composed of the monomers shown in the table.
- monosaccharide, disaccharides, and polysaccharides; quick energy for the cell.
- and a little O.
- sometimes S.
