What are monomers and polymers in DNA?
DNA is a 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.
Is DNA a monomer or macromolecule?
nucleotides
DNA and RNA are polymers (in the case of DNA, often very long polymers), and are made up of monomers known as nucleotides.
What is the monomer for DNA?
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 macromolecules is DNA?
Macromolecule
| Macromolecule (Polymer) | Building Block (Monomer) |
|---|---|
| Nucleic acids | |
| DNA | Nucleotides (a phosphate, ribose, and a base- adenine, guanine, thymine, or cytosine) |
| RNA | Nucleotides (a phosphate, ribose, and a base- adenine, guanine, uracil, or cytosine) |
| Polysaccharides | Monosaccharides |
How are macromolecules polymers and monomers related?
Monomer is a word made of two parts, mono means one, and mer means unit, so monomers are the building units of the polymers. Macromolecules are polymers. Macromolecules in biology refers to the major categories of molecules that make the cell which are the proteins, carbohydrates, lipids and nucleic acids.
What is the monomer of this macromolecule?
Comparing the Biological Macromolecules
| Macromolecule | Basic Formula, key features | Monomer |
|---|---|---|
| Proteins | CHON −NH2 + −COOH +R group | Amino acids |
| Lipids | C:H:O Greater than 2:1 H:O (carboxyl group) | Fatty acid and glycerol |
| Carbohydrates | C:H:O 1:2:1 | Monosaccharides |
| Nucleic Acids | CHONP pentose, nitrogenous base, phosphate | Nucleotides |
Is DNA a macromolecule?
Today, his discovery is known as deoxyribonucleic acid (DNA). Nucleic acids are macromolecules, which means they are molecules composed of many smaller molecular units. Thes units are called nucleotides, and they are chemically linked to one another in a chain.
What is the polymer of DNA?
DNA. DNA is a polymer made from four different monomers , called nucleotides . These join together in different combinations to make long strands. In a DNA molecule , two strands wrap around each other to form a double helix structure.
What are lipids monomer?
Glycerol and fatty acids are the monomers of lipids. Lipids include waxes, oils and fats.
What is the relationship between monomers and polymers?
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. Polymers are chains with an unspecified number of monomeric units.
What is the monomer and polymer of lipids?
Lipids – polymers called diglycerides, triglycerides; monomers are glycerol and fatty acids. Proteins – polymers are known as polypeptides; monomers are amino acids.
How do monomers combine to form macromolecules?
Most macromolecules are made from single subunits, or building blocks, called monomers. The monomers combine with each other via covalent bonds to form larger molecules known as polymers. In doing so, monomers release water molecules as byproducts.
What are the four macromolecules and their polymers?
The four classes of macromolecules are carbohydrates, proteins, nucleic acids, and lipids. These biomolecules can also be referred to as polymers.
What are some examples of monomers and polymers?
Lipids – polymers called diglycerides, triglycerides; monomers are glycerol and fatty acids Proteins – polymers are known as polypeptides; monomers are amino acids Nucleic Acids – polymers are DNA and RNA; monomers are nucleotides, which are in turn consist of a nitrogenous base, pentose sugar, and phosphate group
What are the monomers that make up each of the polymers?
Monomers form polymers by forming chemical bonds or binding supramolecularly through a process called polymerization. Sometimes polymers are made from bound groups of monomer subunits (up to a few dozen monomers) called oligomers .
