A
To synthesize new DNA strands by adding nucleotides to a pre-existing strand
B
To initiate the replication process by creating RNA primers

D
To unwind the DNA double helix
Verified step by step guidance1
Understand the process of DNA replication: DNA replication is the process by which a cell duplicates its DNA before cell division. It involves several enzymes and steps to ensure accurate copying of the genetic material.
Identify the role of DNA polymerase: DNA polymerase is a crucial enzyme in DNA replication. Its primary function is to synthesize new DNA strands by adding nucleotides to a pre-existing strand, ensuring the new strand is complementary to the template strand.
Differentiate between the roles of other enzymes: Other enzymes involved in DNA replication include helicase, which unwinds the DNA double helix, and ligase, which seals gaps between Okazaki fragments on the lagging strand.
Recognize the importance of RNA primers: RNA primers are short sequences of RNA that provide a starting point for DNA polymerase to begin synthesis. They are created by the enzyme primase.
Conclude the primary role of DNA polymerase: Based on the understanding of DNA replication, the primary role of DNA polymerase is to synthesize new DNA strands by adding nucleotides to a pre-existing strand, making it essential for the replication process.
