Answer and Explanation: DNA is classified as a polymer as it consists of numerous nucleotide units. Thus the monomer of DNA is a nucleotide of which there are four, and DNA is termed a polynucleotide because of the repeating phosphate-sugar backbone structure of the molecule.

What is the name of the bond between a monomer and a nucleotide?
When a monomer of nucleic acid- nucleotide binds with the adjacent nucleotide with a phosphodiester bond it is called a dimer of nucleic acid or dinucleotide.
What is the genetic code for a bundle of nucleotides?
Genetic code: A bundle of three nucleotides encodes one amino acid (trinucleotide or three nucleotides, not three base pairs). After the end of transcription, an mRNA is formed which only has the long chain of nucleotide monomer that encodes amino acids. All the non-coding sequences are removed.
What are the properties of nucleic acid?
Properties of nucleic acid: 1 It is acidic in nature. It accepts paired electrons and donates protons. 2 The nucleic acid is overall negatively charged due to the presence of a negative charge on the backbone of it. 3 It does not have its own color or odor. 4 The nucleic acid is insoluble in alcohol thus can be precipitated using it. It can also be precipitated using HCl or acetic acid. 5 It can be easily dissolved in hot water. 6 DNA is a double-stranded and antiparallel molecule so DNA is more stable than RNA.
Why is nucleic acid negatively charged?
The nucleic acid is overall negatively charged due to the presence of a negative charge on the backbone.
What are the components of DNA?
In general, either DNA or RNA– nucleic acids are made up of the three major components- sugar, phosphate, and nitrogenous bases . Purines and pyrimidines are present as nitrogenous bases in DNA while ribose and deoxyribose are present in RNA and DNA respectively.
