W4 DNA replication

Question 1

Replicon:

Answer 1

-Unit of DNA in which individual acts of replication occur
-Each replicaon only fires once per cell cycle
-Each has an origin where replication initiates and a terminus where it stops
-Any sequence not separated from an origin by terminus is replicated as part of the replicon

Question 2

DNA replication in bacteria:

Answer 2

-Replicon origins and surrounding sequences do 3 things:
-Initiate the replication cycle
-Control frequency of initiation
-Control segregation to daughter cells

Question 3

Replication fork:

Answer 3

-Where the parental duplex separates into 2 parental strands during replication
