Answer:
The correct answer is option E. "direct repair using photolyase has removed many of the pyrimidine dimers from the DNA in an error-free manner, so there are fewer lesions for SOS repair to process".
Explanation:
Photolyase is a type of enzyme that catalyses DNA repair from damage caused by exposure to ultraviolet light. Photolyase requires activation by exposure visible light, particularly from the violet end of the visible spectrum. If the Petri plates of the bacteria exposed to UV are located in an incubator that is closely at a large sunny windows, it is very likely that the bacteria is performing direct DNA repair using its photolyase enzymes.
D.) a unicellular organism that has a simple structure and is commonly found in human intestines.
