Correct Answer - Option 4 : DNA

The correct answer is DNA.

  • DNA is responsible for controlling the hereditary characters of the living cells.
  • DNA:
    • Deoxyribonucleic acid is a molecule made up of two polynucleotide chains that coil around each other to form a double helix carrying genetic instructions for the development, functioning, growth and reproduction of all known organisms and many viruses.
    • DNA and ribonucleic acid (RNA) are nucleic acids.
    • Alongside proteins, lipids and complex carbohydrates (polysaccharides), nucleic acids are one of the four primary types of macromolecules that are essential for all known forms of life.

  • Enzyme:
    • Enzymes are proteins that act as biological catalysts.
    • Catalysts accelerate chemical reactions.
    • The molecules upon which enzymes may act are called substrates, and the enzyme converts the substrates into different molecules known as products.
  • Hormone:
    • A hormone is any member of a class of signalling molecules in multicellular organisms, that are transported to distant organs to regulate physiology and/or behaviour.
    • Hormones are required for the correct development of animals, plants and fungi.
  • RNA:
    • Ribonucleic acid is a polymeric molecule essential in various biological roles in coding, decoding, regulation and expression of genes.
    • RNA and deoxyribonucleic acid are nucleic acids.
