Question

Which of the following is NOT a monomer?

a. a glucose molecule
b. an amino acid
c. a protein
d. a nucleotide

Answer 1

A monomer is the basic unit of a polymer that when repeated, forms a complex unit now with different properties. Example is the polysaccharide with a monomer of a monosaccaride such as glucose. Protein is not a monomer since it can be divided still into smaller units called amino acids.

Answer 2

The correct answer is protein.

Protein is not a monomer because it can be divided into small units which are referred to as amino acids.

Monomer is termed as a molecule which undergoes polymerization. Monomers can be classified to different ways. For example, glycine versus caprolactam are examples of classification of natural versus synthetic monomers.

Homopolymer is being got from polymerization kind of monomer.
