Cell Cycle
This is the phase in which the cell spends the longest time in during the Cell Cycle
Interphase
List the phases of mitosis in the correct order
Prophase, Metaphase, Anaphase, Telophase
Name one reason your body might use stem cells
answers may vary
During which phase of interphase does DNA replicate?
S-phase
Name two reasons cells might divide
In which phase of the cell cycle does Telophase occur?
Mitosis
Mitosis results in two genetically identical _______ cells
Daughter
If an owl has 22 chromosomes in each of its body cells, how many chromosomes will be in each daughter cell after mitosis?
22
This occurs during the cell cycle just before the cell enters the G2 stage
DNA Replicates
This process produces genetically identical daughter cells
Mitosis
A student is looking for evidence that spindle fibers separate chromosomes to opposite sides of the cell. Which phase of mitosis would prove this?
Anaphase
Explain why a liver cell and muscle cell look and act differently?
Certain genes are expressed or repressed
Describe what a gene is
a section of DNA
All cells have the same DNA, but look and act differently. How is this possible?
Different genes are activated
Cancer is created by cells over-replicating. Which phase of the cell cycle is skipped to cause this over-replication?
G0 Phase
During which phase of mitosis does the nuclear envelope dissolve (dissapear)?
Prophase
This is the factor that determines what type of specialized cell is produced from stem cells
Gene activation/ genes that are expressed
After DNA replication, the new models are semi-conservative meaning half of the strand is ___ and the other half is ___
original/old, new
Another name for Mitosis is...
M-phase
Name ALL phases of the cell cycle (each part of interphase and mitosis included)
G1 phase, S Phase, G2 phase, Prophase, Metaphase, Anaphase, Telophase, Cytokinesis, G0 phase
During which phase do the spindle fibers dissolve?
Telophase
If a cell cannot activate a certain gene, what might happen?
It will fail to develop any specialized structure or function
Name the four DNA bases and match them accordingly
Adenine (A) ---> Thymine (T)
Cytosine (C) ---> Guanine (G)
Cell differentiation gets needed information from and is regulated by ____
DNA
