What are the polymers of a nucleic acid?
A nucleic acid is a polymeric macromolecule made up of repeated units of monomeric ‘nucleotides’ composed of a nitrogenous heterocyclic base which is either a purine or a pyrimidine, a pentose (five carbon) sugar (either ribose or 2′-deoxyribose), and one to three phosphate groups.
What are the monomers for nucleic acids?
Nucleic acids are long chains of monomers (nucleotides) that function as storage molecules in a cell. Nucleotides are composed of sugar, a phosphate group, and a nitrogenous base. ATP, DNA and RNA are all examples of nucleic acids.
What are the two polymers of nucleic acids?
Nucleic acids are the polymers themselves, the most common of them being DNA and RNA.
What is the monomer and polymer of DNA?
nucleotides
DNA consists of two long polymers (called strands) that run in opposite directions and form the regular geometry of the double helix. The monomers of DNA are called nucleotides. Nucleotides have three components: a base, a sugar (deoxyribose) and a phosphate residue.
How are nucleic acid polymers formed?
DNA and RNA polymers are constructed by forming phosphodiester bonds between nucleotides. This arrangement is called the “sugar-phosphate backbone” of DNA or RNA; the bases hang off to the side. In the cell, DNA or RNA polymers are synthesized using nucleoside triphosphate monomers as precursors.
What is A lipid monomer?
Glycerol and fatty acids are the monomers of lipids. Lipids include waxes, oils and fats. Let’s take a brief look at how fatty acids are composed. A fatty acid is made of a carboxyl group with a chain of carbons attached.
Are nucleotides polymers or monomers?
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 are polymers and monomers?
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 the three examples of nucleic acids?
deoxyribonucleic acid ( DNA)
What elements make up nucleic acid?
The phosphate groups allow the nucleotides to link together, creating the sugar-phosphate backbone of the nucleic acid while the nitrogenous bases provide the letters of the genetic alphabet. These components of nucleic acids are constructed from five elements: carbon, hydrogen, oxygen, nitrogen, and phosphorous.
What are some facts about nucleic acids?
Nucleic acids are the molecules that code the genetic information of organisms. The two nucleic acids used in the repair, reproduction and protein synthesis are deoxyribonucleic acid (DNA, shown) and ribonucleic acid (RNA).
What organic molecule is closely related to nucleic acids?
Nucleic Acids. Nucleic acids, which are composed of nucleotides, are very large and complex organic molecules that contain the genetic code for that organism. Two closely related types are needed to transmit the genetic information from parent to offspring: DNA and RNA. Not surprisingly, they also share structural similarities.
