What properties does Silicon share with carbon that would make silicon based life more likely than say neon based life or aluminum based life?
Si has four valence electrons, the same number as carbon. Therefore, silicon would be able to form long chains, including branches, that could act as skeletons for organic molecules. It would clearly do this much better than neon (with no valence electrons) or aluminum (with three valence electrons).
How is diversity achieved in polymers?
Polymers are linked together with covalent bonds through dehydration synthesis. Condensation (dehydration) is when a water molecule is removed. Explain how organic polymers contribute to biological diversity: Polymers make up DNA and proteins, so any variation in polymers will vary DNA and proteins, as well.
What is an example of a monomer?
What are examples of monomers? Examples of the monomers are glucose, vinyl chloride, amino acids, and ethylene. For example, in glucose, glycosidic bonds that bind sugar monomers to form polymers such as glycogen, starch, and cellulose.
What is another name for polymers?
n. polyurethane, polyamide, silicone, synthetic resin, lignin, trimer, rna, polymeric amide, dna, copolymer, silicone polymer, ribonucleic acid, polyurethan, deoxyribonucleic acid, Desoxyribonucleic Acid.
What is the importance of being a polymer for biomolecules?
Organic polymers play a crucial role in living things, providing basic structural materials and participating in vital life processes. For example, the solid parts of all plants are made up of polymers. These include cellulose, lignin, and various resins.
Which biomolecule is most important?
nucleic acids
What are the 4 biomolecules and their purpose in life?
There are four major classes of biological macromolecules (carbohydrates, lipids, proteins, and nucleic acids), and each is an important component of the cell and performs a wide array of functions. Combined, these molecules make up the majority of a cell’s mass.
What is the role of a monomer?
A monomer is a molecule that forms the basic unit for polymers, which are the building blocks of proteins. Monomers bind to other monomers to form repeating chain molecules through a process known as polymerization. Monomeric proteins are protein molecules that combine to form multi-protein complexes.
What are the 4 types of monomers?
There are four main types of monomer, including sugars, amino acids, fatty acids, and nucleotides.
How do you identify a monomer?
Monomers are the individual units that make up a polymer. We can determine what the monomer is by first finding the smallest repeating structure.
What is the difference between a monomer and a molecule?
is that molecule is (chemistry) the smallest particle of a specific element or compound that retains the chemical properties of that element or compound; two or more atoms held together by chemical bonds while monomer is (chemistry) a relatively small molecule which can be covalently bonded to other monomers to form a …
What is another name for dehydration synthesis?
Dehydration synthesis (condensation reaction) between sugar molecules.
What is a monomer of 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). The sugar and phosphate create a backbone down either side of the double helix.
What is difference monomer and polymer?
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 are examples of polymer?
Examples of synthetic polymers include nylon, polyethylene, polyester, Teflon, and epoxy. Natural polymers occur in nature and can be extracted. They are often water-based. Examples of naturally occurring polymers are silk, wool, DNA, cellulose and proteins.
Which is bigger monomer or polymer?
A monomer is a single atom, small molecule, or molecular fragment that, when bonded together with identical and similar types of monomers, form a larger, macromolecule known as a polymer.
Is DNA a monomer or 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.
What type of polymer is DNA?
polynucleotide
What is the evidence that DNA is a polymer?
What is the evidence from the diagram that DNA is a polymer? DNA is a polymer due to the fact it contains multiple repeating units (monomers). These monomers are known as nucleotides. Multiple nucleotides join together by phosphodiester bonds to form the polymer that is DNA.
What are the 3 parts of that monomer?
Just like in DNA, RNA is made of monomers called nucleotides. Each nucleotide is made up of three components: a nitrogenous base, a pentose (five-carbon) sugar called ribose, and a phosphate group. Each nitrogenous base in a nucleotide is attached to a sugar molecule, which is attached to one or more phosphate groups.
What is a chain of monomers called?
Only $2.99/month. Amino. A protein is composed of a long chain of monomers called _____acids.
What are 4 nitrogen bases?
Four different types of nitrogenous bases are found in DNA: adenine (A), thymine (T), cytosine (C), and guanine (G).
What are the 3 components 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.
