Macromolecules in the Cell Can Be Made from Their Monomers

question 26

Multiple Choice

Macromolecules in the cell can be made from their monomers using one of two polymerization schemes. One is called head polymerization, in which the reactive bond required for polymerization is carried on the end of the growing polymer. In contrast, in tail polymerization, the reactive bond is carried by each monomer for its own incorporation. In the figure, indicate the polymerization scheme and the type of macromolecule.

• A) Head polymerization of a protein
• B) Tail polymerization of a protein
• C) Head polymerization of a polysaccharide
• D) Head polymerization of a nucleic acid
• E) Tail polymerization of a nucleic acid
