What is the primary function of DNA polymerase during DNA replication?
A
It removes RNA primers from the newly synthesized DNA strand.
B
It synthesizes new DNA strands by adding nucleotides to a template strand.
C
It unwinds the DNA double helix to initiate replication.
D
It seals gaps between 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 replication is the process by which a cell duplicates its DNA, ensuring that each new cell receives a complete set of genetic instructions.
Recognize that DNA polymerase is an enzyme that plays a crucial role in synthesizing new DNA strands. It adds nucleotides to the growing DNA strand by using the original DNA strand as a template.
Identify the specific function of DNA polymerase: it catalyzes the formation of phosphodiester bonds between nucleotides, effectively elongating the DNA strand. This process occurs in the 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 seals gaps between Okazaki fragments on the lagging strand.
Conclude that the primary function of DNA polymerase during DNA replication is to synthesize new DNA strands by adding nucleotides to a template strand, ensuring accurate and efficient replication of the genetic material.
