Chapter 12 The Cell Cycle
In this chapter, 24 questions are new, and 12 have been altered to incorporate new material from the
textbook. As in the other chapters, any questions that depend on figures or introductory scenarios have
been placed at the end of the chapter rather than in concept sequence.

4) For a newly evolving protist, what would be the advantage of using eukaryote-like cell division rather
than binary fission?
A) Binary fission would not allow for the formation of new organisms.
B) Cell division would allow for the orderly and efficient segregation of multiple linear chromosomes.
C) Cell division would be faster than binary fission.
D) Cell division allows for lower rates of error per chromosome replication.
E) Binary fission would not allow the organism to have complex cells.
