1What protein regulates the
cell cycle?
Cyclin
2In which phase of mitosis are
the chromosomes split in half?
Anaphase
3Name the 5 phases of the M-phase!
Prophase, Metaphase, Anaphase, Telephase, and Cytokenisis
4Define apoptosis and give an
example.
Programmed cell death (such as the space between your toes)
5Two chromotids are connected
in the middle by the __________.Centromere
6If a cell enters Interphase with
6 chromatids – how many chromatids will it have during metaphase?
12 chromatids
7During the cell cycle how do you know if its an animal cell or a plant cell?
Plant cell forms a cell plate during cytokinesis
8When do chromosomes first appear in the cell cycle?
Prophase
9What is an advantage of
asexual reproduction?
Rapid growth
10What is the function of the
centriole?
Organize the Spindle fibers
11During which stage of mitosis
do the spindle fibers attach to the centromere?
Metaphase
12Programmed Cell death is called ________.
Apoptosis
13In eukaryotic cells, what do cyclins do?
Regulate the timing of the cell cycle.
14Embryonic stem cells are
found in _____________ cells.PluripotentMultipotentTotipotentSimplepotent
Pluripotent
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
