Answer to relevant QuestionsIn a few sentences, explain how a motile bacterium is able to sense the direction of an attractant and move toward it. What evidence exists that supports the idea that the major organelles of eukaryotes were once Bacteria. Calculate the surface-to-volume ratio of a spherical cell 15 mm in diameter and of a cell 2 mm in diameter. What are the consequences of these differences in surface-to-volume ratio for cell function? 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. Describe the key molecular processes that occur when a cell grows and divides.
