1. The GC content of Micrococcus is 66-75% and of Staphylococcus is 30-40 % moles, from this information would you conclude that these organisms are related? Include an explanation of why GC content is a viable method by which to identify the relatedness of organisms. - In your explanation of "why", include information of why we are able to use genetic techniques to identify organisms or determine their relatedness, and specifically why GC content can help determine these. 2. Explain the basis for identification using DNA fingerprinting.-relate this to Microbiology not to human fingerprinting. Why does this technique work? Mention restriction enzymes and their function. 3. A dichotomous key works by determining positive and negative reactions to different biochemicals. Why does this method allow us to identify one species of organism from another? - for this question, do not describe the dichotomous key procedure, think about why it works, what are biochemical reactions based on? Think enzymatic pathways, what are enzymes, what are they a reflection of?
