What are examples of nucleic acid polymers?
Nucleotides. DNA and RNA are polymers (in the case of DNA, often very long polymers), and are made up of monomers known as nucleotides. When these monomers combine, the resulting chain is called a polynucleotide (poly- = “many”).
What are the 2 nucleic acid polymers?
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.
What is a nucleic polymer?
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.
Do nucleic acids have a polymer?
Nucleic acids are actually polymer themselves. The term polymer simply describes a macromolecule like a nucleic acid or protein. The distinguishing characteristic of polymers is that they are made up of smaller constituent parts, and these sequential parts are referred to as monomers.
Why is nucleic acid a polymer?
A polymer is a large molecule that is built up from multiple smaller building blocks in a repetitive manner. The building blocks of the nucleic acids DNA and RNA are nucleotides (see image). The nucleotides have a phosphate group, a sugar group and a nitrogenous base (adenine, thymine, guanine, cytosine or uracil).
What is the polymer and monomer of nucleic acids?
Groups of Monomers and Polymers Nucleic Acids – polymers are DNA and RNA; monomers are nucleotides, which are in turn consist of a nitrogenous base, pentose sugar, and phosphate group.
Are nucleotides polymers?
DNA and RNA molecules are polymers made up of long chains of nucleotides.
What is nucleic acid polymer and monomer?
Nucleic Acids – polymers are DNA and RNA; monomers are nucleotides, which are in turn consist of a nitrogenous base, pentose sugar, and phosphate group. Carbohydrates – polymers are polysaccharides and disaccharides*; monomers are monosaccharides (simple sugars)
What are monomers and polymers of nucleic 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 polymer do nucleotides form?
RNA is a linear polymer of nucleotides linked by a ribose-phosphate backbone. Polymerization of nucleotides occurs in a condensation reaction in which phosphodiester bonds are formed.
What is an example of a nucleic acid monomer?
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. No matter what science class you are in, you will always hear about ATCG when looking at DNA. Uracil is only found in RNA.
How do nucleic acids form polymers?
DNA and RNA polymers are constructed by forming phosphodiester bonds between nucleotides. In this arrangement, a phosphate group acts as a bridge between the 5′ position of one sugar and the 3′ position of the next. This arrangement is called the “sugar-phosphate backbone” of DNA or RNA; the bases hang off to the side.
What is the monomer and polymer for nucleic acid?
How is DNA 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.
