In which phase of the cell cycle does the first step of mitosis occur?
cytokenisis
prophase
interphase
anaphase
When looking at a diagram of the telophase, what seems to be happening?
chromosones gather at opposite ends of cells
nuclear membrane disappears
cell starts to pinch/seperate
chromosones start to form a start shape
The telophase is the (a) step of mitosis.
What is the end product of cytokenisis?
two "daughter cells"
two "daddy cells"
cells connecting
chromosomes separating
What are the steps of mitosis in order?
Interphase, Prophase, Metaphase, Anaphase, Telophase
Anaphase, Metaphase, Prophase, Telophase
Prophase, Metaphase, Anaphase, Telophase
mitosis only has one step.
Steps of the cell cycle in order:
Interphase, prophase, metaphase, anaphase, telaphase, cytokenisis
Anaphase, Cytokenisis, Interphase, Metaphase, Prophase, Telophase
There's only one step.
The cell cycle is not real.
What are chromosones?
The things that help us breath.
tightly coiled strands of dna
dog dna
powerhouse of the cell.
Multicellular organisms have:
one cell
multiple cells
no cells
cancer
Genes help:
us breath
make mitochondria
code for DNA
What is so special about a stem cell?
carry out specific functions
They are not specialized.
differ in structure
Specialized cells have:
no DNA
no specific function
specific functions they're made to carry out
What would happen if there was no cell specialization?
Every cell in your body would look the same.
The ribosomes would turn human
The cells would specialize
What does it mean to be pluripotent?
to have many potentials; be capable of giving rise to several cell types
to have one potential; be capable of giving rise to only one cell type
to produce and distribute cell powerhouses; make and give the mitochondria to cells.
What does it mean to be unipotent?
to have many potentials; be capable of giving rise to several cell types
to have one potential; be capable of giving rise to only one cell type
to produce and distribute cell powerhouses; make and give the mitochondria to cells.
Gene regulation does what?
give rise to only one cell type
Turn on and off genes in response to environmental stimuli or other factors
give rise to any cell type
If all your cells have the same DNA, how do they end up having different structures and functions?
gene expression
gene regulation
photosynthesis
Gene expression is the process of...
turning on cells
expressing(translating) dna into protein (within specialized cells)
turining off cells
Stem cells are (a) , having ability to give rise to any type of cell.
Specialized cells are (a) , having ability to only give rise to one type of cell.
