F. interphase
_______ 7. single-celled prokaryotes divide through this process
G. centrioles
_______ 8. the total endowment of DNA that is unique to each species
H. centromere
_______ 9. the sequence of events from the beginning of one cell division to the
I. mitosis
beginning of the next
J. cytokinesis
Name the Phase (Be Specific – for example: S phase of Interphase) – you may use answers more than once.
_______________________________________10. DNA replication occurs
_______________________________________11. chromosomes uncoil into their tangled state of DNA and protein
_______________________________________12. microtubules begin assembling into the mitotic spindle
_______________________________________13. appearance of two daughter nuclei at the two poles
_______________________________________14. completion of cleavage furrow or cell plate
_______________________________________15. subcellular organelles replicate
_______________________________________16. chromosomes align on equatorial plane
_______________________________________17. nuclear envelope is highly fragmented which allows the microtubules to interact with the
chromatids
_______________________________________18. microtubules move chromosomes to opposite poles of the cell
Use the following diagrams to answer questions 19 – 21.
______________________________________19. Which stage of the cell cycle are these cells in?
______________________________________20. What is “A” pointing to?
______________________________________21. What is “B” pointing to?
22. ________ One of the major differences in the cell division of prokaryotic cells compared to eukaryotic cells is that..
a. cytokinesis does not occur in prokaryotic cells
b. DNA is not replicated in prokaryotic cells
c. duplicated chromosomes are attached to the nuclear membrane in prokaryotic cells and are separated from each other as the
membrane grows
d. the chromosomes do not separate along a mitotic spindle network in prokaryotic cells
e. the chromosome number is reduced by half in eukaryotic cells but not in prokaryotic cells
23. ________ Sister chromatids…
a. have one-half the amount of genetic material as does the original chromosome
b. start to move along spindle fibers toward opposite poles during telophase
c. slide past each other along non kinetochore microtubules
d. are formed during prophase
e. line up on the equator of the cell during anaphase
