What are DNA properties?
The information in DNA is stored as a code made up of four chemical bases: adenine (A), guanine (G), cytosine (C), and thymine (T). An important property of DNA is that it can replicate, or make copies of itself. Each strand of DNA in the double helix can serve as a pattern for duplicating the sequence of bases.
What proves 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.
Why is DNA A polymer GCSE?
DNA (deoxyribonucleic acid) is a polymer which is essential for life. Most DNA is a double helix, where two polymer chains are lined up and then twisted around each other. The DNA polymer is made from four different types of monomer , which are called nucleotides .
Why do different polymers have different properties?
Because of the structure of the molecules, polymeric materials have different properties compared to other materials, like metals. Specifically, the relatively high molecular weight and long polymer chain length result in entanglement, and the lack of covalent intermolecular bonds facilitates polymer chain mobility.
What are the properties and functions of DNA?
DNA or deoxyribonucleic acid is the basic hereditary material present in all the cells of an organism and basically provides a blue print for the cell’s functions, growth, reproduction and death. The structure of the DNA called the double-stranded helical structure was first described by Watson and Crick in 1953.
Is DNA a 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 is a DNA polymer?
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.
What is a DNA polymer made of?
nucleotides
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 is A DNA polymer?
Is DNA an addition 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. The first man-made polymers were actually modified versions of these natural polymers.
What determines polymer properties?
Polymer properties depend on the chemicals that the polymer is made from and polymerization conditions that ultimately set molecular architecture: chemical linkage type, chain length, and the nature of the end groups. The type of the monomer-repeat unit that forms a polymer has a strong effect on polymer properties.
What properties do different polymers have?
Sandwich bags, carpets, nylon stockings, stackable chains, milk cartons, etc. Why do different polymers have different properties? Answer: They have different chemical compositions (different monomer units), different structures, different ways of being fabricated, etc.
How are the physical properties of DNA maintained?
Physical Properties. In living organisms such as humans, DNA exists as a pair of molecules rather than a single molecule. These strands are entwined in the shape of a double helix and the helix is kept stable by hydrogen bonds, which can be found between the bases attached to the two strands.
How are DNA, starch, proteins and polymers made?
Addition polymers are made from molecules containing C=C bonds. Polymers have different properties and uses but it is difficult to dispose of them. DNA, starch and proteins are biological polymers. Biological polymers are made naturally by living organisms. DNA is a polymer made from four different monomers, called nucleotides.
How many monomers are there in a DNA molecule?
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.
How are polymers made naturally by living organisms?
Biological polymers are made naturally by living organisms. 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. Starch is a polymer made from sugar monomers.
