DNA replication stress leads to DNA damage and genome instability in part because of the unique structure of replicating DNA molecules ( Figure 2).When single-strand lesions occur in non-replicating molecules of DNA, the overall integrity of chromosomes is maintained by hydrogen bond base pairing on either side of these lesions until they are repaired ( Figure 2 A). You can change your ad preferences anytime. During initiation, the DNA is made accessible to the proteins and enzymes involved in the replication process. The three phases of replication process are: (1) Initiation (2) Elongation and (3) Termination. Due to sheer size of chromosome in eukaryotes, chromosome chromosome contains multiple origin of replication. DNA replication would not occur without enzymes that catalyze various steps in the process. They are known as pol α, pol β, pol γ, pol δ, and pol ε. Is DNA replication conservative, semi-conservative or random dispersed? Histones must be removed and then replaced during the replication process, which helps to account for the lower replication rate in eukaryotes. Enzymes called DNA polymerases catalyze DNA synthesis.
