摘要: ABSTRACT Excision repair is a major set of pathways by which damage removed from DNA; mutations that affect excision result in large increases (5–10 fold) UV sensitivity mammalian cells. Mutations excision-repair indirectly, or the cell cycle, DNA chain growth, replicon organization, etc., may smaller (2–4 sensitivity. The rate depends on nature and location damaged sites their relationship to chromatin Structure functional state DNA. involves nicks relax supercoiling prevent initiation, thus indirectly affecting replication. Perturbations replication are coupled cell's capacity “post-replication repair” merely be descriptive term for these perturbations not discrete system.
