14 Questions
What is the role of the DnaA protein in DNA replication?
Causing DNA to stretch and separating the strands
What is the function of the DnaB helicase in DNA replication?
Continuing the unwinding of DNA by breaking hydrogen bonds
What is the function of single-strand DNA-binding protein (SSBP) in DNA replication?
Preventing rejoining of the DNA strands
What are replication forks in DNA replication?
Junctions between double-stranded and unwound single-stranded DNA
What is the function of the DnaB helicase in DNA replication?
Continuing the unwinding of DNA by breaking hydrogen bonds
What is the role of single-strand DNA-binding protein (SSBP) in DNA replication?
Binding to single-stranded regions to prevent strands from rejoining
What happens as more DnaA proteins bind to the unwound DNA?
DnaA proteins are released from the DNA
What defines a replication bubble in DNA replication?
Region where DNA appears like a bubble
What is the primary function of DnaC helicase loader proteins?
Helping load DnaB helicase onto unwound DNA
How many replication forks are formed at the origin of replication?
Two
What is the significance of the replication forks in DNA replication?
They move in opposite directions
Where do DnaA proteins and DnaB-DnaC complex bind during DNA replication?
At the origin of replication
What prevents the DNA strands from rejoining during replication?
Single-strand DNA-binding protein (SSBP)
Which protein is responsible for continuing the unwinding of DNA by breaking hydrogen bonds?
DnaB helicase
