Which type of biological molecule would control cell activities? A) Amino Acids.
C) Nucleic Acids.
B) Lipids.
D) Carbohydrates.

C. Nucleic Acids.

Explanation:

Nucleic acids are thus uniquely capable of directing their own self-replication, allowing them to function as the fundamental informational molecules of the cell. The information carried by DNA and RNA directs the synthesis of specific proteins, which control most cellular activities.
