Question

which of the following is not a characteristic of proteins?
a contain genetic information
b catalyze chemical reactions
c can allow movement
d can bind to foreign substances and target them for destruction
e can transport materials

Explanation:

To determine which is not a protein characteristic, analyze each option:

• Option b: Enzymes (proteins) catalyze reactions.
• Option c: Motor proteins (e.g., actin, myosin) enable movement.
• Option d: Antibodies (proteins) bind to foreign substances for destruction.
• Option e: Transport proteins (e.g., hemoglobin) move materials.
• Option a: Genetic information is stored in nucleic acids (DNA/RNA), not proteins. Thus, "contain genetic information" is not a protein characteristic.

Answer:

a. contain genetic information
