What is the major advantage of electron microscopes over light microscopes? What type of electron microscope would be used to view the three- dimensional features of a cell?
Answer to relevant QuestionsHow large can a prokaryote be? How small? Why is it that we likely know the lower limit more accurately than the upper limit? What are the dimensions of the rod- shaped bacterium Escherichia coli? Assume you are given two cultures, one of a species of gram-negative Bacteria and one of a species of Archaea. Discuss at least four different ways you could tell which culture was which. DNA molecules that are AT-rich separate into two strands more easily when the temperature rises than do DNA molecules that are GC-rich. Explain this based on the properties of AT and GC base pairing. In Chapter 10 we will learn about mutations, inheritable changes in the sequence of nucleotides in the genome. By inspecting Table, discuss how the genetic code has evolved to help minimize the impact of mutations. Describe the role of proteins present at the divisome. Does the FtsZ ring form before or after chromosome replication?
