Which statement best describes a protein?

A) a polymer made up of 100 or more amino-acid monomers

B) a polymer made up of 3000 or more glucose monomers

C) a polymer made up of 100 or more glucose monomers

D) a polymer made up of 20 or more amino-acid monomers

Respuesta :

A polymer made up of 20 or more amino-acid monomers

Answer: Option (D) is the correct answer.

Explanation:

Proteins are basically three-dimensional structure which are made up of number of monomers of amino-acids. These are also referred as polymers which are specifically polypeptides.

The amino acids are arranged in different combinations so there are 20 amino acid monomers arranged in different combinations.

Thus, we can conclude that the statement  a polymer made up of 20 or more amino-acid monomers best describes a protein.
