Verified step by step guidance1
Understand the process of DNA replication: DNA replication is the process by which a cell duplicates its DNA, resulting in two identical copies. This is crucial for cell division.
Identify the role of each enzyme listed: DNA polymerase, RNA polymerase, Ligase, and Helicase each have specific functions in the cell.
Focus on DNA polymerase: DNA polymerase is the enzyme responsible for synthesizing new strands of DNA by adding nucleotides to the growing DNA strand during replication.
Differentiate DNA polymerase from RNA polymerase: RNA polymerase is involved in transcription, not replication. It synthesizes RNA from a DNA template.
Consider the roles of Ligase and Helicase: Ligase joins Okazaki fragments on the lagging strand, while Helicase unwinds the DNA double helix. Neither synthesizes new DNA strands.
