Prokaryotic vs eukaryotic replication fork

WebAug 3, 2024 · The rescue of stalled DNA replication forks is essential for cell viability. Impeded but still intact forks can be rescued by atypical DNA helicases in a reaction known as fork regression. This reaction has been studied at the single-molecule level using the Escherichia coli DNA helicase RecG and, separately, using the eukaryotic SMARCAL1 … WebJul 13, 2024 · Replication process in eukaryotic and prokaryotic organisms share a lot similarity with few differences.
