Question
6. (9 pts) In an environmental system that received benzene contamination, the presence of a series of genes encoding for the biodegradation of benzene was verified. However, benzene biodegradation was not observed (i.e., benzene concentrations remained constant in the system). What are the possible reasons for the lack of biodegradation? Provide three possible answers (that are distinctly different!) based on topics discussed in class during Lectures 4 and 5. Provide answers in whole sentences and not just key words-make sure to explain how each of your answers leads to no biodegradation.Explanation / Answer
The biodegradation of benzene has not occurred even in the presence of genes coding for the same. This can be due to following reasons,
