SnapShot: Tolerating replication stress.

Completion of DNA replication relies on the ability of replication forks to traverse various types of DNA damage, actively transcribed regions, and structured DNA. The mechanisms enabling these processes are here referred to as DNA damage tolerance pathways. Here, we depict the stalled DNA replication fork structures with main DNA transactions and key factors contributing to the bypass of such blocks, replication restart, and completion.
