SOS repair

(redirected from error-prone repair)

SOS re·pair

a system that repairs severely damaged bases in DNA by base excision and replacement, even if there is no template to guide base selection. This process is a last resort for repair and is often the cause of mutations.
Synonym(s): error-prone repair
An error-prone repair system that functions when E coli’s DNA is damaged by bond-breaking physical agents, thymine starvation, toxins, chemicals—e.g., mitomycin C—and UV light

Scientists from NATO member countries introduce new theoretical developments and instrumentation for the non-invasive sensing and imaging of damage in vegetation related to stress from ultraviolet light; identify the cell biological hazards of ultraviolet radiation coupled with other environmental stresses; and examine how ultraviolet light may relate to the production of nitric oxide by plants in terms of DNA damage, error-prone repair cell cycles, and the multiple mechanisms of programmed cell death.
