Are the protists a monophyletic group? please discuss this and describe this by drawing a “tree” that would include the diatoms, dinoflagellates, red algae, brown algae, green algae and charophytes. what are the main characteristics of these different groups, i.e., which of these groups have silica in its cell walls? Which has both chlorophyll a and b,which of these is considered in the plantae group but NOT a green plant, etc.?

Describe how you would identify genes responsible for transcription in E. coli by isolating mutations in their genes. Remember that these genes are required for cell viability. Include all the steps in the isolation of the mutants and also describe how you will differentiate the mutants you want from those in other genes necessary for viability. This includes giving me the expected result for mutants in the genes you want.
