Question

What biological macromolecule is made up of monomers like the one shown below?

A. Carbohydrate
B. Nucleic acid
C. Fat
D. Protein

Answer 1

B

Step-by-step explanation:

A nucleic acid is composed of a pentose sugar that has a nitrogenous base at C2 and a phosphate molecule at C5. To form DNA, nucleic acid monomers are joined together in phospho-diester bonds. The phosphate at C5 of one monomer form a bond with the C1 of the next monomer.
