What various functions do proteins have in a cell?—ANSWER-Proteins may facilitate the
movement of materials in or out of a cell. Some can act as enzymes that catalyze, or speed
up, biochemical processes. Others play a structural role while other proteins, such as
filaments, enable movement.
What are the two major types of nucleic acids and their roles?—ANSWER-There are two
major types of nucleic acids: DNA (deoxyribonucleic acid) and RNA (ribonucleic acid). Nucleic
acids are chemical molecules that carry genetic information within the cell. DNA contains a
