What is the primary function of DNA polymerase in DNA replication?
A
To remove RNA primers from the newly synthesized DNA strand
B
To unwind the DNA double helix
C
To synthesize new DNA strands by adding nucleotides to a pre-existing chain
D
To join Okazaki fragments on the lagging strand
Verified step by step guidance
1
Understand the role of DNA polymerase in the context of DNA replication. DNA polymerase is an enzyme that plays a crucial role in the synthesis of new DNA strands.
Recognize that DNA replication involves the creation of a new DNA strand complementary to the template strand. This process requires the addition of nucleotides to a pre-existing chain.
Identify that DNA polymerase adds nucleotides to the 3' end of the growing DNA strand, ensuring that the new strand is synthesized in a 5' to 3' direction.
Differentiate the function of DNA polymerase from other enzymes involved in DNA replication, such as helicase, which unwinds the DNA double helix, and ligase, which joins Okazaki fragments on the lagging strand.
Conclude that the primary function of DNA polymerase is to synthesize new DNA strands by adding nucleotides to a pre-existing chain, which is essential for accurate DNA replication.
