1. Which type of cell undergoes both mitosis and meiosis?
a) Eukaryotic
b) Prokaryotic
c) Both
2. What are the three phases of interphase? If a cell is not in interphase, what phase of the
cell cycle must it be in?
3. Cell division requires the division of two things in the cell. What are the names of the two
processes of division that occur in order for a cell to divide?
4. Circle the two components of chromosomes?
a) Protein
b) RNA
c) DNA
d) Carbohydrate
e) Lipid
5. Chromosomes are __________ during interphase and _________during karyokinesis.
a) Condensed, Extended
b) Extended, Condensed
c) Straight, Bent
d) Bent, Straight
6. What are the five phases of mitosis and briefly describe what occurs at each phase?
a)
b)
c)
d)
e)
7. How does the number of chromosomes and DNA content in a cell containing 2
chromosomes compare to the original cell in G1 of interphase following each phase of
mitosis? (G1 Interphase – 2 chromosomes and the equivalent DNA content – no sister
chromatids) **There are two cells produced after telophase & cytokinesis, I only want
you to compare the number of chromosomes and DNA content in one cell.
a) Prophase –
b) Prometaphase –
c) Metaphase –
d) Anaphase –
e) Telophase & Cytokinesis –

9. How does the number of chromosomes and DNA content in a cell containing 2
chromosomes compare to the original cell in G1 of interphase following each phase of
meiosis listed? (G1 Interphase – 2 chromosomes that have not been replicated yet)
**Note that the second half of meiosis occurs twice producing four cells but I only want
you to compare the number of chromosomes and DNA content for one of the cells.
a) Meiosis I (Prophase – Anaphase) –
b) Meiosis I (Telophase & Cytokinesis) –
c) Meiosis II (Prophase – Metaphase) –
d) Meiosis II (Anaphase) –
e) Meiosis II (Telophase & Cytokinesis) –
10. How many different gametes can be produced for an organism containing 4 homologous
chromosomes (2N = 8)?
11. What are recombinant chromosomes?
