When DNA is copied during the cell cycle
A group of enzymes that bond new nucleotides together
It copies DNA so that cells can form new cells
Explain the function of replication
It specifies what nucleotides go together in the sequence
How does DNA act as its own template during replication
The DNA polymerase can detect the error in the strand and corrects it
How do cells ensure that DNA replication is accurate?
They unzip the double helix, hold the double helix apart and the DNA polymerase enzyme forms the bond between the nucleotides
What are the jobs of the enzymes and proteins during replication?
Helicase: Enzymes begin to unzip the double helix at numerous places along the chromosome, called origins of replication
What is the 1st step of the replication process?
Primase: Primes the open strand to start adding the new nucleotides
What is the 2nd step of the replication process?
DNA polymerase: Free floating nucleotides pair, one by one, with the bases on the template strands as they are exposed
What is the 3rd step of the replication process?
Ligase: Connects the short fragments on the lagging strand and two identical DNA molecules result
What is the 4th step of the replication process?
