Step 1
Damaging effect of ultraviolet light on bacteria: Ultraviolet (UV) light, specifically UV-C, has a damaging effect on bacteria by causing the formation of pyrimidine dimers in their DNA. This leads to errors in DNA replication and transcription, which can Show more…

Marisa A.
A bacterial culture has been exposed to UV radiation, and the cells are preparing to repair the DNA damage. A) Describe two DIFFERENT mechanisms of repair used by E. coli to repair UV-induced DNA damage. Do not just name the mechanisms; provide some details and name molecules/proteins involved. B) Would you expect the bacteria to be able to repair more or less of the damage if they were placed in a dark environment after UV damage? Justify exactly why you answered in this way.
