protein p2 Flashcards
Which enzyme is responsible for adding nucleotides during DNA replication?
DNA polymerase.
What role does helicase play in DNA replication?
It unwinds the DNA double helix.
How does DNA polymerase ensure accuracy during replication?
By proofreading and correcting errors.
What happens at the replication fork during DNA replication?
DNA strands are unwound.
What is the role of RNA primers in DNA replication?
To initiate the synthesis of new DNA strands.
What is the significance of the sugar-phosphate backbone in DNA?
It provides structural support.
What does it mean for DNA replication to be semi-conservative?
Each new DNA molecule contains one old and one new strand.
What are Okazaki fragments?
Short sequences of DNA synthesized on the lagging strand.
Why is it important for cells to replicate their DNA accurately?
To prevent mutations.
What is the primary purpose of DNA replication in cells?
To ensure each daughter cell receives a complete set of DNA.
