    Which of the following are the constituents of nucleic acid? Sugar ...
    • Nucleic acid, naturally occurring chemical compound that is capable of being broken down to yield phosphoric acid, sugars, and a mixture of organic bases (purines and pyrimidines). Nucleic acids are the main information-carrying molecules of the cell, and, by directing the process of protein synthesis, they determine the inherited characteristics of every living thing.
    • The two main classes of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). DNA is the master blueprint for life and constitutes the genetic material in all free-living organisms and most viruses. RNA is the genetic material of certain viruses, but it is also found in all living cells, where it plays an important role in certain processes such as the making of proteins.
    • Each nucleotide has three components: a 5-carbon sugar, a phosphate group, and a nitrogenous base.
    • The DNA does not include a potassium base and hence only option 4 is not correct.

    Which of the following are the constituents of nucleic acid? Sugar ...


    Constituents of Nucleic Acid:

    - Sugar: One of the constituents of nucleic acid is a sugar molecule, specifically deoxyribose or ribose. This sugar forms the backbone of the nucleic acid molecule.

    - Phosphate: Another important constituent of nucleic acid is the phosphate group. Phosphate groups are responsible for linking the sugar molecules together in the nucleic acid chain.

    - Nitrogenous Base: Nitrogenous bases are the third major constituent of nucleic acid. These bases include adenine, thymine, cytosine, guanine (in DNA) and uracil (in RNA). They are responsible for the genetic information encoded in the nucleic acid molecule.

    Therefore, the correct answer is option C - 1, 2 and 3 only. Potassium base is not a constituent of nucleic acid.
