Each nucleotide is made up of:

Correct answer: C. Three subunits

  • A. One subunit
  • B. Two subunits
  • C. Three subunits
  • D. Four subunits

Explanation

A nucleotide is the basic building block of nucleic acids, such as DNA and RNA. It consists of three essential components: a pentose sugar (either ribose or deoxyribose), a nitrogenous base (such as adenine, thymine, cytosine, guanine, or uracil), and a phosphate group. Each of these components plays a crucial role in the structure and function of nucleic acids. Options A, B, and D are incorrect because they do not accurately reflect the number of subunits in a nucleotide.

About Biological Molecules

The chapter covers water's polarity and biological roles, carbohydrates, lipids, proteins and nucleic acids, including their monomers, bonds, structures and functions. It also distinguishes RNA from DNA and explains conjugated molecules such as glycoproteins, glycolipids and nucleoproteins, which combine organic molecules with a non-protein component.
