What is a zygote?
a mutated gene
A fertilized egg cell
A gene that has been switched off
A bacteria that eats genes
Why does each cell in your body have the same DNA?
Proteins tell the cells what DNA they need
Ribosomes tell the cells what DNA they need
Your brain tells each cell what DNA they need
They all came from the same original zygote cell
Through what process does the original zygote cell multiply?
mitosis
meiosis
DNA replication
Gene duplication
Which cells in your body have the same DNA?
Nerve and germ cells
All somatic cells in every human on earth
Germ cells and muscle cells
All somatic cells in one person's body
How are genes like light switches?
They need an electric current to work
They can be turned on and off
They need to be attached to a power source
They often become disconnected and don't work
What is cell differentiation?
When stem cells form into their specified types of cells around the body
When somatic cells multiply into more cells
When an egg becomes fertilized by a sperm
When the body heals its own wounds
How is it possible that liver cells and eyeball cells have the same DNA?
The nerve cells make the liver and eyeball cells
Liver cells can turn into eyeball cells
Eyeball cells can turn into liver cells
Both liver and eyeball cells originally came from the same first cell
Why do liver cells and eyeball cells have different functions?
The brain controls all of their individual functions
Only their shape decides what roles the cells fulfill
Different genes were activated in their DNA, turning them into different cells with different functions
Their location in the body is the only thing that decides their function
What is an embryonic stem cell?
A stem cell present in the body after the organism has become an adult
An unspecified cell in an embryo that can turn into any type of somatic cell
An unspecified cell in the body present after birth
A specific type of somatic cell, such as a skin cell or a muscle cell
How do embryonic stem cells turn into specific types of cells?
Only specific genes are turned on and off, which make give directions to make specific proteins in each cell
The brain sends signals to change each cell into what they're supposed to be
As the embryo grows in the womb, the mom's cells help tell what the embryo cells need to turn into
It's all luck
What are the stem cells present in a body after many years called?
Somatic cells
Embryonic stem cells
Germ cells
Adult stem cells
Which stem cells can only turn into cells specific to the region their in?
All stem cells
Adult stem cells
Embryonic stem cells
No stem cells do this
Which cells flip their genes on and off to turn into specific cells?
Embryonic stem cells present after birth
Germ cells
Stem cells
Somatic cells
What is determination?
When stem cells become specific types of body cells
When the zygote divides into more cells
The moment each stem cell's future path is decided
When the sperm and egg combine to make one cell
Can somatic cells switch their roles? (such as a skin cell turn into a nerve cell)
Yes, anytime the subconscious says so
Yes, but only when the body is in extreme danger
No, but germ cells can
No, somatic cells can never switch their roles
What is one of the results of only certain parts of a cell's genes being switched on?
Only certain proteins are made, allowing differentiation
The cell begins to replicate immediately
A cell undergoes meiosis
Cells combine to form one fetus
What types of somatic cells are going to be made based on these genes?
Skin cells
Muscle cells
Nerve cells
None of these
When are embryonic stem cells a part of the body?
All throughout someone's life
Only when the organism is an embryo
Only after birth
Before fertilization
What type of cells can adult bone stem cells make?
Bone cells
Only more bone stem cells
Bone and germ cells
Any cell the body needs
What are the different types of stem cells?
Egg stem cells
Adult stem cells
Genetic stem cells
Embryonic stem cells
Which cells are involved in differentiation?
Embryonic stem cells
Adult stem cells
Somatic cells
Germ cells
What happens to the original zygote's DNA after differentiation?
It changes based on what cell results after differentiation
It is copied and used in every single cell in the body
It goes away after it is finished with its job
It is dissolved in the cytoplasm
What is the process where cells find out their future functions?
Differentiation
Gene therapy
Determination
Mitosis
Which cells act as health reserves for the body?
Embryonic stem cells
Adult stem cells
Germ cells
Somatic cells
