Question 1 - 10
• This is the process by which a cell divides into
2 daughter cells.
Answer 1 – 10
• What is cell division?
Question 1 - 20
• Collectively, this part of the cell cycle includes
the G1, S and G2 phases. They are the
“intermediate” phases between periods of cell
division.
Answer 1 – 20
• What is interphase?
Question 1 - 30
• When chromosomes replicate, they form
these. It looks like an “x” shape.
Answer 1 – 30
• What are sister chromatids?
Question 1 - 40
• This is the area where sister chromatids
attach. When the spindle forms, this is the
part of the sister chromatids that binds to the
spindle.
Answer 1 – 40
• What is the centromere?
Question 1 - 50
• This is a protein that regulates the timing of
the cell cycle.
Answer 1 – 50
• What is a cyclin?
Question 2 - 10
• The cell cycle consists of this many phases?
Answer 2 – 10
• What are four?
Question 2 - 20
• Cell division occurs in the M phase of the cell
cycle. It is made up of these two parts?
Answer 2 – 20
• What are mitosis and cytokinesis?
Question 2 - 30
• These two phases of the cell cycle control the
growth of cells, in between periods of division.
Answer 2 – 30
• What are the G1 ad G2 phases?
Question 2 - 40
• These are the phases of the cell cycle, in order.
Answer 2 – 40
• What are M, G1, S and G2?
Question 2 - 50
• Chromosome replication occurs during this
phase of the cell cycle.
Answer 2 – 50
• What is the S phase?
Question 3 - 10
• Mitosis is the division of the nucleus. This is
the division of the cytoplasm.
Answer 3 – 10
• What is cytokinesis?
Question 3 - 20
• Mitosis occurs during this phase of the cell
cycle.
Answer 3 – 20
• What is M phase?
Question 3 - 30
• This is the longest phase of mitosis.
Chromosomes condense, the nuclear
envelope disappears and the centrioles form a
spindle across the cell.
Answer 3 – 30
• What is prophase?
Question 3 - 40
• During this phase, the sister chromatids split,
becoming two individual chromosomes. They
begin to move to opposite ends of the cell.
Answer 3 – 40
• What is anaphase?
Question 3 - 50
• Cytokinesis usually happens at the same time
as this phase of mitosis
Answer 3 – 50
• What is telophase?
Question 4 - 10
• Cytokinesis is the division of the cytoplasm.
This is the division of the nucleus.
Answer 4 – 10
• What is mitosis?
Question 4 - 20
• This is the acronym for the four phases of
mitosis.
Answer 4 – 20
• What is PMAT?
Question 4 - 30
• During this phase, the sister chromatids line
up across the center of the cell and their
centromeres attach to the spindle.
Answer 4 – 30
• What is metaphase?
Question 4 - 40
• During this phase, the spindle disappears
nuclear envelopes re-form around the two
new sets of chromosomes.
Answer 4 – 40
• What is telophase?
Question 4 - 50
• During cytokinesis, animal cell membranes
simply draw in and pinch off, creating two new
cells. However, in plant cells, this structure
forms as a precursor to the cell wall.
Answer 4 – 50
• What is the cell plate?
Question 5 - 10
• Uncontrolled cell growth can cause this
disease?
Answer 5 – 10
• What is cancer?
Question 5 - 20
• This is a form of cancer treatment where toxic
chemicals are used to alter the cell cycle of
cancerous cells.
Answer 5 – 20
• What is chemotherapy?
Question 5 - 30
• There are two types of cyclin drugs. Internal
regulators respond to events inside the cell
while these respond to signals outside the
cell.
Answer 5 – 30
• What are external regulators?
Question 5 - 40
• When functioning properly, this gene is in
charge of pausing cell division until all DNA is
properly copied.
Answer 5 – 40
• What is the p53 gene?
Question 5 - 50
• Cyclins are a family of proteins that regulate
the timing of the cell cycle. When injected into
non-dividing cells, the cells will then do this
Answer 5 – 50
• What is divide?
