1
What
protein regulates the cell
cycle?
Cyclin
2
In
which phase of mitosis are
the chromosomes split in half?
Anaphase
3
Name
the 5 phases of
the M-phase!
Prophase, Metaphase,
Anaphase, Telephase,
and Cytokenisis
4
Define
apoptosis and give an
example.
Programmed cell
death (such as the
space between your
toes)
5
Two
chromotids are connected
in the middle by the __________.
Centromere
6
If
a cell enters Interphase with 6
chromatids – how many
chromatids will it have during
metaphase?
12 chromatids
7
During the cell cycle how do
you know if its an animal cell
or a plant cell?
Plant cell forms a cell
plate during
cytokinesis
8
When do chromosomes first
appear in the cell cycle?
Prophase
9
What
is an advantage of
asexual reproduction?
Rapid growth
10
What
is the function of the
centriole?
Organize the Spindle fibers
11
During
which stage of mitosis
do the spindle fibers attach to
the centromere?
Metaphase
12
Programmed
Cell death
is called ________.
Apoptosis
13
In eukaryotic cells, what do
cyclins do?
Regulate the timing of the cell
cycle.
14
Embryonic
stem cells are found
in _____________ cells.
Pluripotent
Pluripotent
Multipotent
Totipotent
Simplepotent
15
Why
does cancer happen?
Cells have lost their ability to
to control cell growth.
16
 In
normal cells what causes cells
to stop dividing?
Growth factors or external
regulators (when they are
surrounded by other cells)
17
Mitosis and Cytokinesis are the only
phases of the ____________.
M-phase
18
Stem cell research is controversial when
cells from the _______________ are used.
Embryonic or pluripotent cells
19
What causes cancer cells to
metastasize?
Move into the blood stream
and spread.
20
What ratio of surface area to volume is
best for cells? 6:1, 3:1, or 2:1?
6:1
21
If the volume of the cell is too large,
what will happen to it’s waste?
The waste will be too large to
find ways out of the cell –
waste will build up.
22
When is demand on the DNA too
great to function properly?
When surface area to volume
ratio is too small.
23
In which phase does the cell
experience the most growth?
G1
24
In prokaryote cells, how are cells
replicated?
From 1 parent cell dividing
into 2 identical cells
25
What is the shortest phase of
mitosis?
Metaphase
