Sometimes DNA replication hits a 🛑 roadblock. Cells don’t stop; they take clever detours (DNA damage tolerance) 🚗💨 to keep genomes intact. That’s the focus of our new review in @cp-trendsbiochem.bsky.social: “Just bypass it: mechanisms of DNA damage tolerance” 🔗 doi.org/10.1016/j.ti...

It is not always safe to repair DNA Damage. Sometimes, cells "just bypass it". During DNA replication, repair of lesions on DNA can be dangerous. Cells instead "tolerate" DNA damage and focus on finishing replication. Read our review and find out why and how: doi.org/10.1016/j.ti...
