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 and RNA are composed of monomers termed as nucleotides.
What is the polymer of nucleic acids?
The two main classes of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). If the sugar is ribose, the polymer is RNA; if the sugar is the ribose derivative deoxyribose, the polymer is DNA.
What are lipids monomers?
Glycerol and fatty acids are the monomers of lipids. Lipids include waxes, oils and fats.
How are the monomers in nucleic acids joined quizlet?
The monomers of all nucleic acids. Each nucleotide is formed by bonding together a phosphate group, a sugar molecule and a nitrogenous base. … A purine base has two carbon nitrogen rings joined together. A pyrimidine only has one carbon-nitrogen ring.What are polymer monomers?
Monomers are small molecules, mostly organic, that can join with other similar molecules to form very large molecules, or polymers. … Polymers are a class of synthetic substances composed of multiples of simpler units called monomers. Polymers are chains with an unspecified number of monomeric units.
Are nucleotides monomers?
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).
What are the 4 types of monomers?
Monomers are atoms or small molecules that bond together to form more complex structures such as polymers. There are four main types of monomer, including sugars, amino acids, fatty acids, and nucleotides.
Is DNA a monomer or polymer?
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.Is nucleotide a monomer or polymer?
The monomer units of DNA are nucleotides, and the polymer is known as a “polynucleotide.” Each nucleotide consists of a 5-carbon sugar (deoxyribose), a nitrogen containing base attached to the sugar, and a phosphate group.
How are the monomers in nucleic acids joined?They are joined to one another by covalent bonds between the phosphate of one and the sugar of another. These linkages are called phosphodiester linkages. Phosphodiester linkages form the sugar-phosphate backbone of both DNA and RNA.
Article first time published onWhat are the polymers of nucleic acids quizlet?
Nucleic Acids is a polymer made of monomers called nucleotides.
Is dipeptide a polymer?
As we noted for nucleic acids, a polymer is a chain of subunits, amino acid monomers linked together by peptide bonds. … A molecule formed from two amino acids, joined together by a peptide bond, is known as a dipeptide.

What is the monomer for phospholipids?
A lipid is a biological molecule that dissolves (is soluble) in nonpolar solvents, and the monomers of lipids are fatty acids and glycerol.
What are 3 nucleic acids examples?
- deoxyribonucleic acid (DNA)
- ribonucleic acid (RNA)
- messenger RNA (mRNA)
- transfer RNA (tRNA)
- ribosomal RNA (rRNA)

What are the monomers and polymers of lipids?
Lipids – polymers called diglycerides, triglycerides; monomers are glycerol and fatty acids. Proteins – polymers are known as polypeptides; monomers are amino acids.
Are amino acids monomers?
Amino acids are the monomers used to build the chains that eventually become proteins. There are approximately 20 – 22 different common amino acids. Key concepts: all but one of the common amino acids have the same general structure.
How many different kinds of monomers are there in nucleic acids?
There are five easy parts of nucleic acids. All nucleic acids are made up of the same building blocks (monomers). Chemists call the monomers “nucleotides.” The five pieces are uracil, cytosine, thymine, adenine, and guanine.
Is cytosine a monomer?
DNA is composed of four amino acids: adenine, guanine, thymine and cytosine. Each nucleotide, or monomer, has different attributes that allow it to link with the corresponding nucleotide and form a long chain, or sequence.
What are the monomers that make up cellulose?
Cellulose is made of glucose monomers in the beta form, and this results in a chain where every other monomer is flipped upside down relative to its neighbors. Image modified from OpenStax Biology. Unlike amylose, cellulose is made of glucose monomers in their β form, and this gives it very different properties.
Is nucleotide a nucleic acid?
A nucleotide is the basic building block of nucleic acids. RNA and DNA are polymers made of long chains of nucleotides. 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.
Which of the following nucleic acids are composed of nucleotides?
The two main types of nucleic acids are DNA and RNA. Both DNA and RNA are made from nucleotides, each containing a five-carbon sugar backbone, a phosphate group, and a nitrogen base.
Are nucleosides monomers of nucleic acids?
They are monomeric units of nucleic acids and also serve as sources of chemical energy (ATP, GTP), participate in cellular signalling (cAMP, cGMP) and function as important cofactors of enzymatic reactions (coA, FAD, FMN, NAD+). The molecule without the phosphate group of nucleotides is called as nucleoside.
How nucleic acids are formed?
Nucleic acids are formed when nucleotides come together through phosphodiester linkages between the 5′ and 3′ carbon atoms. … They are composed of monomers, which are nucleotides made of three components: a 5-carbon sugar, a phosphate group and a nitrogenous base.
What are the 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 elements are in nucleic acids?
Nucleic acids such as DNA and RNA contain carbon, hydrogen, oxygen, nitrogen, and phosphorus (CHON P). The body also needs trace amounts of other elements such as calcium, potassium, and sulfur for proper functioning of muscles, nerves, etc.
Why is a nucleic acid a monomer?
Nucleic acids are just groups of nucleotides that bonded together by hydrogen-bonding. So we say that nucleotides are monomers of nucleic acids. A nucleotide is made up of three components, a nitrogenous base, a phosphate (PO3−4) group, and a 5 -carbon sugar.
What are the monomers of lipids quizlet?
glycerol is a three carbon alcohol. Monomer of lipids. It is composed of glycerol and 3 fatty acid chains. Glycerol forms the backbone of fat.
Is phospholipid a monomer or polymer?
Fatty acids are lipid monomers that consist of a hydrocarbon chain with a carboxyl group attached at the end. Fatty acids form complex polymers such as triglycerides, phospholipids, and waxes.
Is dipeptide a monomer or polymer?
Define these terms: peptide bond: A covalent bond in which two amino acids are joined by a dehydration reaction. dipeptide:A polymer of two amino acids linked by a peptide bond. polypeptide:A polymer of many amino acids linked by a peptide bond.
