Round 1
Vocabulary
Question 1
• Non-reproductive cells in the body, such
as a skin or muscle cell, are referred to as
what type of cell?
Question 2
• How many chromosomes do human
diploid cells have?
Question 3
• The complex of DNA and proteins that
condense to form chromosomes during
cell division is referred to as ________?
Question 4
• The narrow portion of a chromosome
where two sister chromatids are attached
is referred to as the ________________.
Question 5
• The division of the cytoplasm is
called________.
Question 6
• The type of division that results in haploid
non-identical daughter cells is
called________.
Question 7
• Chromosomes align along the
______________ plate during metaphase
of mitosis.
Question 8
• When homologous chromosomes are
pulled together tightly during Prophase I of
Meiosis it is referred to as a ________.
Crossing over may occur as a result.
Question 9
• In animal cells during cytokinesis a
_________ forms during the process of
cytokinesis.
Question 10
• Microtubules attach to the __________ of
chromosomes during mitosis and meiosis
II. This allows sister chromatid to be
pulled apart and moved to opposite ends
of the cell.
Round 2
Mitosis
Question 1
• What phase of the cell cycle makes up the
greatest portion of a cell’s life?
Question 2
• I.D. the phase represented by letter A.
Question 3
• I.D. the structure represented by # 1
Question 4
• Prokaryotes, such as bacteria, reproduce
by a type of mitosis referred to as
_________.
Question 5
• A cell plate begins to form in _______ cells
during _______ (phase name).
Question 6
• DNA is replicated during which point of
Interphase?
Question 7
• Chromosomes line up along the equator of
the cell during which phase of mitosis?
Question 8
• I.D. the phase in which the cell indicated
below is in.
Question 9
• I.D. the phase in which the cell indicated
below is in.
Question 10
• I.D. the phase in which the cell indicated
below is in.
Round 3
Cancer
Question 1
• True or False: All cells divide at
approximately the same rate.
Question 2
• Which checkpoint of the cell cycle seems
to be the most important? If the cell
passes through this checkpoint, it typically
continues through the cell cycle and will
eventually divide.
Question 3
• What will a call do if it does not receive the
go-ahead signal at one of the checkpoints,
of the cell cycle?
Question 4
• What do you call a cyclin-Cdk complex (as
seen below) that triggers a cell’s passage
past the G2 into the M phase of the cell
cycle?
Question 5
• Cyclin concentration will be the highest at
which of the following stages of the cell
cycle?
M, G1, S, or G2
Question 6
• If kinetochores do NOT attach to spindle
microtubules a signal will be sent that
delays what phase of mitosis?
Question 7
• PDGF stimulates the division of fibroblast
cells in culture. PDGF is an example of a
______________.
Question 8
• What do you call a tumor of abnormal cells
that does not move from the original site?
Question 9
• What do we call the process of cancerous
cells invading nearby tissues?
Question 10
• Animal cells typically must be attached to
a substratum in order to divide. This is a
type of external signal known as
_____________?
