Which of following can form a biopolymer?
Correct answer: D. All of these
- A. Amino acid
- B. Nucleotides
- C. Monosaccharides
- D. All of these
Explanation
Option D is correct. Biopolymers are large molecules made up of repeating units of smaller molecules. Amino acids are the repeating units of proteins, which are the most abundant biopolymers in the human body. In the case of nucleotides, the monomers are linked together by phosphodiester bonds to form nucleic acids, which are the genetic material of all living organisms. Monosaccharides are the monomers that make up biopolymers called polysaccharides. Polysaccharides are very important molecules in living organisms. They are used for energy storage, structural support, and cell signaling.

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.
