Within the following dialogue and in lecture we shall be involved in beginning to look at how the method of dna replication is completed whereas preserving in thoughts a number of the driving questions. A replication fork is shaped which serves as a template for replication. Forks meet on the dna replication terminus reverse the origin of replication, and the result’s two separate and full round chromosomes.
