Embryonic cell cycles allow the rapid division of cells in the early embryo.  These mitotic cell cycles are much shorter in length than the mitotic cell cycles of cells in a mature organism.  In the embryonic cell cycles, mitosis takes approximately the same amount of time as it does in the cell cycles of mature cells.  What do you think is a result of the embryonic cycle?  

A.  Resulting daughter cells are smaller than the mother cell in the embryonic cell cycles. B.  Resulting daughter cells do not contain the same genetic information as the mother cell in the embryonic cell cycles. C.  Resulting daughter cells cannot form a mitotic spindle in the embryonic cell cycle. D.  Mother cells in the embryonic cell cycle spend the majority of their time in G0.

You expose a tube of bacteria to ultraviolet radiation to induce mutations. You then spread the bacteria on a plate containing media with all known required nutrients and wait until separate colonies form. Finally, you use replicate plating to transfer a print of this plate to an additional sterile plate containing minimal media plus a known required nutrient for the bacteria. Based on this protocol, colonies growing on the plate with minimal media would include what type of cells?  

A.  only wild-type bacteria B.  only mutant bacteria C.  mutants that only require the supplied nutrient D.  Both wild-type and all mutants E.  wild-type bacteria and the mutants that only require the supplied nutrient Clarify Question · What is the key concept addressed by the question? · What type of thinking is required?
