Stages of Mitosis
Cell Cycle
An ordered sequence of events in the life of a cell
Cancer
An unregulated cell cycle causes _______. This means that there is an uncontrolled growth and division of cells.
Decreases
As a cell gets bigger, what happens to the surface area to volume ratio
G2
At what stage is DNA replicated and cell size checked?
G1
Checks for DNA damage and cell size
Chromosome Chromatin
Curly Not curly
Cleavage furrow
Cytoplasmic division in animal cells
Cell plate
Cytoplasmic division in plant cells
Plant=cell plate Animal=cleavage furrow
Difference of cytokinesis in plants and animals?
Cytokinesis
Final stage of the cell cycle: the division of the cytoplasm to form two separate daughter cells immediately after mitosis.
Prophase
First phase of mitosis in which duplicated chromosomes condense and spindle fibers begin to form.
Telophase
The fourth phase of mitosis in which the chromosomes begin to stretch out and lose their rod-like appearance and a new nuclear membrane forms. The two new cells begin to seal off.
Anaphase
The sister chromatids are pulled to opposite poles by shortened microtubels. The chromatids are moving to opposite poles because the centromeres have been divided.
Centriole Spindle Fibers
The spindle fibers are attached to the... They assist the development of...
T
There are two types of stem cells.
Anaphase
Third phase of mitosis in which the chromosomes separate and move to opposite ends of the cell.
Spindle apparatus
This includes the spindle fibers, centrioles, and aster fibers. It moves and organizes the chromosomes before cell division.
cyclin and CDK
What 2 proteins help regulate cell cycle
Prophase, metaphase, anaphase, telephase
What are the four stages of mitosis from first to last?
If the chromosome is attached to the spindle
What is checked during the Metaphase cell regulation?
Prophase
stage of mitosis in which chromatin condense, the nucleolus and nuclear membrane disappear, and the spindle apparatus forms.
Telophase
stage of mitosis in which cytokinesis occurs. The nuclear membrane reforms around the chromosomes. The cytoplasm of the cell divides (cytokinesis, a sub-step of telophase) This is dubbed as the opposite of prophase.
How many daughter cells do you get after mitosis?
2
Cyclin
A protein substrate that joins with cyclin-dependent kinase to regulate different activities during the cell cycle.
Mitosis
A stage of the cell cycle where cell division results in two daughter cells each having the same number and kind of chromosomes as the parent nucleus, typical of ordinary tissue growth.
Membrane
In a cell, the surface includes
Membrane
In a cell, volume doesn't include?
Cytokinesis
In this sub-step of telophase the cytoplasm divides.
Metaphase
Nicknamed "the organization phase", the chromosomes attach to spindle fibers and align along the cell's equator. This is the last stage the chromatids are together
Metaphase
Second phase of mitosis in which the chromosomes line up across the center of the cell.
Interphase
Stage of the cell cycle when a cell grows, replicates DNA, and prepares to go through cell division
T
T/F Stem cells can become more than one type of cell.
T
T/F Stem cells help repair and maintain cells.
Interphase
The chromosomes become invisible, cytokinesis is completed, chromosomes are replicated
to get rid of damaged cells
What is the purpose of apoptosis?
Prophase
When does the nucleus breakdown?
