What happens during mitosis?
A mother cell duplicates (copies) the chromosomes in its nucleus and produces two daughter cell which is different to the mother
A mother cell duplicates (copies) the chromosomes in its nucleus and produces one daughter cell which is different to the mother
A mother cell duplicates (copies) the chromosomes in its nucleus and produces one daughter cell which is identical to the mother
A mother cell duplicates (copies) the chromosomes in its nucleus and produces two daughter cells which are identical to the mother
What do the daughter cells contain?
Chromosomes that contain DNA
Cytoplasmic fluid
A cell wall
Nucleolus
What is DNA?
DNA is the genetic information for cellular function (a cells job)
DNA is the genetic information for growth
DNA is the genetic information for replication
DNA is the genetic information for where they go
What is cytokinesis?
Division of the cell wall
Division of the nucleus
Division of the cytoplasm, which creates two identical cells
Division of the cytoplasm, which creates one identical cell
Is mitosis a form of asexual or sexual reproduction?
Mitosis is a form of asexual reproduction because you end up with identical copies
Mitosis is a form of sexual reproduction because you end up with different copies
What is the cell cycle?
The cell cycle is a series of events that take place in a cell that results in DNA replication
The cell cycle is a series of events that take place in a cell that results in DNA replication and cell division
The cell cycle is a type of cell division
The cell cycle is a series of events that take place in a cell that results in growth of the cell
What are the 4 phases of the cell cycle?
G1 (growth), S(DNA replication), G2 (more growth and prepare for division) and M (cell division)
G1, Metaphase, S, G2
G1, S, G2, Cytokinesis
Interphase, Metaphase, Anaphase, Telophase
What phases make up Interphase?
Mitosis, G1, S
G1, S, Metaphase
G1, S, G2
What happens in the M (Mitosis) phase?
The cell divides and transfers one copy of its DNA to one identical daughter cell
The cell divides and transfers three copies of its DNA to two identical daughter cells
The cell divides and transfers two copies of its DNA to two identical daughter cells
The cell divides and transfers one copy of its DNA to two identical daughter cells
What things are checked at the G1, S, and G2 checkpoints? (3 things)
G1 checks that there is no DNA damage and there are enough resources, S makes sure there is no errors during DNA replication and G2 checks proper cellular function
G1 checks that there is makes sure there is no errors during DNA replication, S makes sure there is no DNA damage and sufficient resources and G2 checks proper cellular function
Where do cells spend most of their time in the cell cycle?
Metaphase
Mitosis
Interphase
Cytokinesis
What happens in G0? What is G0? (3 things)
G0 is a resting phase. Cells are still performing cell functions, and they are preparing to divide. Some cells go there temporarily if they don't have enough resources
G0 is a resting phase. Cells are not performing cell functions, and they're not preparing to divide. Some cells go there temporarily if they don't have enough resources
G0 is a resting phase. Cells are still performing cell functions, but they're not preparing to divide. Some cells go there temporarily if they don't have enough resources
What is apoptosis?
Apoptosis is when a cell self destructs because it took too long to divide
Apoptosis is when a cell self destructs because there is an error that can be fixed
Apoptosis is when a cell self destructs because there is an error that can't be fixed
Apoptosis is when a cell self destructs because it divided to quick
What happens during G1?
The cell grows
The cell replicates its DNA
The cell gets ready to divide
What happens during S phase?
The cell grows
The cell grows and gets ready for cell division
The cell replicates its DNA
What happens in G2 phase?
The cell grows more to get ready for cell division
The cell replicates its DNA
The cell grows
What is DNA?
DNA is genetic information about cancer
DNA is genetic information about the cell cycle
DNA is genetic information about growth
DNA is the genetic information about cellular functions
What is replication?
Replication means to make an exact copy of something
Replication means to make a different copy of something
What is the end result of mitosis?
Two new cells with different sets of chromosomes
Two new cells with identical sets of chromosomes
One cell with two identical sets of chromosomes
One cell with two different sets of chromosomes
What happens to cells if there is an issue that can be fixed?
It goes through apoptosis
It goes into cell limbo, where it pauses until all the resources are available
What happens when a cell is NOT regulated (uncontrolled)?
Nothing happens
The cell grows bigger than usual
The cell can develop errors/mutations, and divide with those harmful mutations which can lead to cancer and tumors
The cell can develop errors/mutations, but won't divide with those harmful mutations
What is the cell cycle in order
S, G1, G2, M
G1, G2, S, M
M, G1, S, G2
G1, S, G2, M
What happens to cells if there is an issue that can't be fixed?
It goes into cell limbo, where it pauses until all the resources are available
It goes through apoptosis
What is an example of cells on the human body that go through mitosis
Skin cells
Blood cells
Bone cells
All of the above
Why is mitosis important to multi-cellular organisms like ourselves
Mitosis is how multi-cellular organisms like ourselves get up in the morning
Mitosis is how multi-cellular organisms like ourselves continue to grow and repair (ie. heal a cut)
Mitosis is how multi-cellular organisms like ourselves walk
Mitosis is how multi-cellular organisms like ourselves do our jobs
Both binary fission and mitosis are forms of asexual reproduction in which a parent cell divides to form two different daughter cells
True
False
Binary fission occurs primarily in eukaryotes (plants and animals and other multi-cellular organisms)
True
False
The main function of binary fission is reproduction
True
False
The main functions for mitosis are reproduction repair (heal cut) and growth (from baby to adult)
True
False
Is binary fission exact all the time?
No, because sometimes the daughter cells get unequal numbers of chromosomes due to DNA replication and separation taking place at the same time
No, because sometimes the daughter cells get unequal numbers of chromosomes due to DNA replication occurring at a different time than DNA replication
Yes, because you get an exact copy every time due to DNA replication and separation taking place at the same time
Yes, because even though the DNA is jumbled all over the place the cell still knows where to clip it
Both binary fission and mitosis are two types of cell division
True
False
Both binary fission and mitosis DNA is copied and separated to form new cells
True
False
In both binary fission and mitosis cytokinesis does not occur
True
False
Why is an error in mitosis a bigger deal than an error in binary fission?
An error in mitosis is a bigger deal because an error will affect how the organism lives. An error in binary fission just makes the bacteria live longer
An error in mitosis is a bigger deal because an error will affect how the organism looks. An error in binary fission just makes the same bacteria, but makes it look different
An error in mitosis is a bigger deal because these cells are instrumental in the growth and repair of a multi-cellular organism. An error will affect an organisms growth and development (repair), while an error in binary fission introduces genetic diversity because that is how bacteria reproduce
An error in mitosis is actually not a bigger deal because mutations are harmful to the reproduction of both
