C. genome
_A______ 4. DNA and protein material that is loosely packed and indistinguishable
D. chromatids
_G______ 5. cytoskeleton component used only in animal cell division
E. cell cycle
_I_____ 6. also known as division of the nucleus
F. interphase
__B_____ 7. single-celled prokaryotes divide through this process
G. centrioles
__C_____ 8. the total endowment of DNA that is unique to each species
H. centromere
_E______ 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.
___S phase of Interphase___________________10. DNA replication occurs
___Telophase____________________________11. chromosomes uncoil into their tangled state of DNA and protein
___Prophase_____________________________12. microtubules begin assembling into the mitotic spindle
___Telophase_____________________________13. appearance of two daughter nuclei at the two poles
___Cytokinesis____________________________14. completion of cleavage furrow or cell plate
___G2 of Interphase________________________15. subcellular organelles replicate
___metaphase____________________________ 16. chromosomes align on equatorial plane
___Prophase______________________________17. nuclear envelope is highly fragmented which allows the microtubules to interact with the
chromatids
___Anaphase______________________________18. microtubules move chromosomes to opposite poles of the cell
Use the following diagrams to answer questions 19 – 21.
__Cytokinesis_________________________________19. Which stage of the cell cycle are these cells in?
__Cleavage furrow_____________________________20. What is “A” pointing to?
__Cell plate___________________________________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
