검증된 단계별 안내1
Begin by understanding the role of DNA helicase in the cell. DNA helicase is an enzyme that unwinds the DNA double helix during DNA replication.
Recall that enzymes are a type of protein. Proteins are biological molecules made up of amino acids and are responsible for catalyzing biochemical reactions.
Consider the options given: Carbohydrate, Lipid, Nucleic Acid, and Protein. Carbohydrates and lipids are primarily involved in energy storage and structural functions, while nucleic acids are involved in genetic information storage and transfer.
Recognize that DNA helicase, being an enzyme, fits the category of proteins, as enzymes are specialized proteins that facilitate specific biochemical reactions.
Conclude that DNA helicase is a protein, as it functions as an enzyme to unwind DNA strands during replication, which is a characteristic function of proteins.
