Overview of DNA Replication
Multiple Choice
In the context of DNA replication, what is the primary function of DNA polymerase?
A
To unwind the DNA double helix by breaking hydrogen bonds between base pairs
B
To synthesize RNA primers needed to initiate DNA synthesis
C
To synthesize a new DNA strand by adding nucleotides to the end of a growing strand using the template strand as a guide
D
To join Okazaki fragments by forming phosphodiester bonds between adjacent DNA segments
Verified step by step guidance1
Identify the role of DNA polymerase in DNA replication by understanding the key activities involved in the process.
Recall that DNA replication requires unwinding the double helix, which is performed by helicase, not DNA polymerase.
Recognize that RNA primers are synthesized by primase, an enzyme distinct from DNA polymerase.
Understand that DNA polymerase's main function is to add nucleotides to the 3\' end of a growing DNA strand, using the existing strand as a template to ensure accurate base pairing.
Note that the joining of Okazaki fragments is carried out by DNA ligase, not DNA polymerase.
