Which of the following molecules is NOT a polymer? A) Deoxyribose B) tRNA C) Insulin D) Starch E) Chitin

The molecule that is NOT a polymer from the given options is A) Deoxyribose.

Here's why:

A polymer is a large molecule that is made up of repeating subunits known as monomers.

A) Deoxyribose is a monosaccharide, not a polymer. It is a simple sugar that is part of the backbone of DNA, but it is not a polymer itself.

B) tRNA is a type of RNA, which is a polymer of nucleotides.

C) Insulin is a protein, and proteins are polymers of amino acids.

D) Starch is a polymer of glucose molecules.

E) Chitin is a polymer of N-acetylglucosamine, a derivative of glucose.
