How might a mutation cause a beneficial effect on protein function? __________ How might a mutation have a harmful effect on protein function? __________ Why does a silent mutation have no apparent affect on an organism? __________ How would the citrate mutation in E. coli give it an advantage over other E. coli populations?

Solution

4). The citrate mutation in E.coli give it an advantage over other E.coli populations because they can feed off citrate, which is the additional food source for these bacteria. So, these bacteria can also survive when only citrate is available, while the other bacteria die from lack of food source.
