Explain how bacteria address the following challenges and which cellular structures or components are involved and how they function. Be complete in your answers. In most instances bacteria have multiple strategies for dealing with these conditions - address as many as you can. • Harmful chemicals in the environment • Lack of moisture • Existence in an aqueous environment • Elevated temperatures • In the case of bacterial animal pathogens, white blood cells that "gobble up" the bacteria (i.e., phagocytes...

4. Development of organelles Aa Aa 3 Modern eukaryotic cells are very complex and have many features that allow them to function efficiently. These complexities took a very, very long time to evolve and likely progressed as a series of small improvements that were naturally selected. For example, modern eukaryotic cells have internal membranes surrounding their organelles and the nucleus. This arrangement likely arose when the cellular membranes of some ancient bacterial cells accidentally folded to become internal membranes. Which...

Bacteria use DNA methylation as a method to label their DNA, so they can identify foreign DNA and degrade it using restriction endonucleases. This DNA methylation is different than that of eukaryotic organisms, in that it adds a methyl group to adenine. This makes the bacterial DNA methylation system a potential antibiotic target. Question 1: (3 marks) Based on what we learned about enzyme activity and regulation, explain what you would expect for the following enzymes: How would this differ...
