Which of the following molecule are not polymeric?

(A) nucleic acid

(B) myoglobulin

(C) cellulose

(D) Proteins

Answers (1)

Nucleic acids are the polymeric chain of nucleotides.

Cellulose is a polysaccharide composed of a linear chain of β-1,4 linked d-glucose units with a degree of polymerization ranging from several hundred to over ten thousand, which is the most abundant organic polymer on the earth.

Myoglobin is a monomer (so it doesn't have a quaternary structure at all). Myoglobin binds oxygen more tightly than does hemoglobin. 

Proteins are polymeric chain of amino acid where the amino acids are linked together by peptide chains.

So, Myoglobin is the correct answer.
