Answer: Option d

Explanation: A nucleotide can be defined as the organic molecules that serves as the monomers for the nucleic acid polymers such as deoxyribonucleic acid and ribonucleic acid.

These are the most essential biomolecules of all the living forms on the earth. They are composed of the three sub units that make up the whole structure.

A nitrogenous base, a five carbon sugar and atleast a phosphate group constitutes to form a nucleotide.

Example: DNA and RNA

In DNA and RNA, a nitrogenous base, sugar, and phosphate groups together are called Nucleotide.

DNA and RNA are molecules that contain genetic information and are made up of nucleotides.

Further Explanation:

Nucleic Acids

  • Nucleic acids are one of the four major bio-molecules in nature. Nuclei acids is divided into two; RNA and DNA.
  • The building blocks of nucleic acids are Nucleotides which are made by a nitrogenous base, a sugar and a phosphate group.

DNA

  • DNA is a nuclei acid that is responsible for carrying genetic information in living organisms.
  • It is through DNA that genetic information is passed from one organism to another through the process of DNA replication.
  • Additionally, it carries the information that is used to make proteins which performs various functions in living cells.
  • Each Nucleotide in DNA contains a nitrogenous base, a deoxyribose sugar, and a phosphate group.
  • DNA molecules are made up of nitrogenous bases; Adenine, Guanine, Cytosine and Thymine.

RNA

  • Ribonucleic acid (RNA) is a type of nucleic acid, a molecule that plays a major role in the flow of information from the DNA to the proteins. For a gene to be expressed information has to be passed through the RNA.
  • Each nucleotide in RNA contains a nitrogenous base, a ribose sugar, and a phosphate group.
  • Nitrogenous bases in RNA includes; Adenine, Guanine, Cytosine and uracil. Thymine in DNA is replaced with Uracil.

Keywords: Nucleic acids, DNA, RNA, Nucleotides, nitrogenous base, sugar, phosphate group.
