Cell Division Exercise 1. What limits cell size? 2. Genetic information is bundled into packages of ____ known as _____ 3. Are multiple chromosomes a feature of prokaryotes or eukaryotes? 4. Is DNA in the cytoplasm a feature of prokaryotes or eukaryotes? 5. Is a single, cicular chromosome a feature of prokaryotes or eukaryotes? 6. Is a membrane-bound nucleus a feature of prokaryotes or eukaryotes? 7. Is DNA inside the nucleus a feature of prokaryotes or eukaryotes? 8. As a result of mitosis, the cells of a multicellular organism share which of these properties 9. In eukaryotic cells, DNA is packaged with proteins into structures called chromosomes. What advantage do chromosomes provide the cell? 10. The drug colchicine inhibits the formation of spindle fibers during mitosis. If you treat dividing plant cells with colchicine, what would you expect the result to be? 11. What happens in the S phase? 12. Cell division occurs in two stages: division of the nucleus, called ____, and division of the cytoplasm, called ____ 13. The cytoplasm pinches in half. The centromeres of the duplicated chromosomes line up across the center of the cell. The cell grows and replicates its DNA and centrioles. The chromosomes which were distinct and condensed begin to spread out into a tangle of chromatin. The genetic material inside the nucleus condenses and the duplicated chromosomes become visible. The chromosomes separate and move along spindle fibers to opposite ends of the cell. 14. As a result of mitosis, the cells of a multicellular organism share what properties?
