The Cell Cycle & Mitosis Study Guide
Reproduction
Vocabulary: Asexual reproduction
1. Why do cells need to reproduce?
The Cell Cycle
Vocabulary: chromatin, chromosome, sister chromatids, centromere, cell cycle, interphase, mitotic phase,
mitosis, cytokinesis, telomeres
1. What are the stages of the cell cycle?
a. G1 phase: what happens?
b. S phase: What happens?
c. G2 phase: What happens?
d. M phase: What happens?
2. Which stage of the cell cycle lasts the longest amount of time?
3. Give examples of the types of cells that divide frequently. Infrequently? Why do some cells divide frequently
and others not at all?
4. Which phases of the cell cycle make up interphase?
a. What form does DNA exist in during interphase?
b. Why must DNA be uncoiled during this phase?
c. What is the role of proteins (histones) in DNA during this phase?
d. How can you tell if a cell is in interphase (microscope work)?

What 2 processes occur during the M phase?
When does DNA condense into chromosomes?
Recognize and distinguish between chromatin, chromosome, chromatids (sister chromatids)
Where are telomeres located? What is their function? How do they influence the aging process?
Mitosis = Cell Division
Vocabulary: prophase, metaphase, anaphase, telophase, cell plate, cleavage furrow, cytokinesis, cancer,
centromeres, spindle fibers
1. What is the function of mitosis?
2. Sequence the stages of mitosis in order.
3. Summarize the main events of each phase.
4. Be able to draw or recognize each stage.
a. Is nuclear membrane or nucleolus visible?
b. Are chromosomes visible in condensed form?
c. Location of chromosomes
5. What is the function of cytokinesis? How does it differ from animal and plant cells?
6. What makes cells cancerous? How/Why do cancer cells lead to sickness?
Other:
How many chromosomes are present in human genome? How many pairs of chromosomes?
What regulates cell size (2 things)?
What is the advantage of a small cell size?
