Total questions: 15
Worksheet time: 15mins
During Anaphase what are separated?
Spindle Fibers
Sister Chromatids
Telomeres
Chromosomes
How is cytokinesis different in plant cells vs. animal cells?
In plant cells, cytokinesis uses a cell plate. In animal cells, cytokinesis uses a cleavage furrow.
In plant cells, cytokinesis uses a cleavage furrow. In animal cells, cytokinesis uses a cell plate.
In plant cells, cytokinesis happens twice, in animal cells cytokinesis happens once
In plant cells, cytokinesis happens once, in animal cells cytokinesis happens twice.
Why do cells go through mitosis?
to make food from sunlight
to create proteins
to get air into the cells
to reproduce, grow and repair/replace
Daughter cells created by mitosis have
half of the parents genetic material
twice the parent cell's genetic material
an exact copy of the parent cell
have a brand new DNA structure
How do multi cellular organisms grow, repair and reproduce cells?
meiosis
mitosis
migrate and differentiate
osmosis
Which of the following lists, in order, the phases of mitosis?
interphase, metaphase, anaphase, telophase
prophase, metaphase, anaphase, telophase
prophase, metaphase, anaphase, interphase
prophase, anaphase, metaphase, telophase
During interphase
DNA lines up in the middle of the cell and DNA attaches to spindle fibers
2 new nuclei form
2 new identical cells are created
DNA gets copied
During prophase
DNA lines up in the middle of the cell and DNA attaches to spindle fibers
centrioles and spindle fibers appear
2 new identical cells are created
DNA gets copied
During metaphase
DNA lines up in the middle of the cell and DNA attaches to spindle fibers
centrioles and spindle fibers appear
2 new identical cells are created
DNA gets copied
During anaphase
DNA lines up in the middle of the cell and DNA attaches to spindle fibers
centrioles and spindle fibers appear
Each DNA gets pull to the opposite sides of the cell
DNA gets copied
During telophase
DNA lines up in the middle of the cell and DNA attaches to spindle fibers
centrioles and spindle fibers appear
Each DNA gets pull to the opposite sides of the cell
2 new nuclei form
During cytokinesis
DNA lines up in the middle of the cell and DNA attaches to spindle fibers
Cell membrane pinches to make 2 new identical daughter cells
Each DNA gets pull to the opposite sides of the cell
2 new nuclei form
Which of the following proteins is primarily responsible for regulating cell size during the cell cycle?
Cyclin
Actin
Tubulin
Myosin
What is the role of the mTOR pathway in cell size regulation?
It inhibits cell growth by degrading proteins.
It promotes cell growth by increasing protein synthesis.
It decreases cell size by reducing nutrient uptake.
It has no role in cell size regulation.
During which phase of the cell cycle does the cell check for DNA damage before proceeding to mitosis?
G1 phase
S phase
G2 phase
M phase
