What happens durring Prophase of Mitosis
-The chromatin condenses
-Break up of the nuclear envelope
-Mitotic spindle is created
Cellular reproduction is not used for?
Production of gametes for sexual reproduction
What happens during Metaphase of Mitosis?
the chromatids are pulled to the center of the cell.
What happens during Anaphase of mitosis?
-mitotic spindle tips the sister chromatids apart
-chromatids are pulled to different sides of the cell
What happens during Telophase of MItosis?
- Nuclear envelope is created
-Mitotic spindle breaks down
Durring Telophase in animals what is the last step?
cleavage furrow is made.
During Telophase in plant cells what is the last step?
a cell plate is created(from the Golgi Aparatus)
Cytokenisis is not a process of what?
Mitosis
What is the Diploid #?
the total number of chromasomes
what has to be in ballance with asexual reproduction?
Apoptosis
What is Apoptosis?
Programed cell death.
The chromatins condence in what part of Mitosis?
Prophase
What is cytokinesis?
when animals cells make cleavage furrows and plant cells make a cell wall between the new cells.
After Mitosis and Cytokinesis are finished what do you get?
Two Identical daughter cells
What stage does the mitotic spindle form in?
Prophase
The Chromatin condenses in what stage of Mitosis?
Prophase
Cytokinesis immediately follows what step in Mitosis?
Telophase
What is the definition of Cancer?
A disease of the cell cycle.
What is a Benign tumor?
Mutated cells that mass in one general location and have not moved.
What is a Malignant Tumor?
Mutated cells that have grown in one location but the cells have started moving throughout the body.
Can you Inherit cancer?
NO, You only pass on the predisposition for cancer.
What are the two processes that Cancer interupts in the cell?
- Apoptosis
- messes with Telomeres
What does Radiation therapy do for cancer patience?
It tries to trigger Apoptosis
What does chemotherapy do?
Attacks the processes of cell repliction for both cancer and health cells.
What is Metastasis?
When the cancer cells break off from the origional tumor and spread though the body.
What is contact Inhibition?
When cells touch each other they are supposed to stop growing.
What is a Proto-Oncogene?
part of the cell that triggers rapid growth/ regeneration.
Crossing over happens durring what phase of Meiosis?
Prophase 1
Independant assortment happens durring what phase of Meiosis
Metaphase 1
What is a bar body?
When one of the X chromosomes inactivate.
Identical twins are ?
Monozygotic
What does Monozygotic mean?
one egg fertilized by 2 sperm cells
What does Dysygotic mean?
There were 2 separate fertilization events. 2 eggs and 2 sperm cells.
Define sister chromatids
Carbon copies on chromosomes
Pair of chromosomes passed on by parents
Homologist pairs
What is a somatic cell?
Every cell in your body accept sex cells
what is a type of cancer of the muscles?
Sarcoma
what is angiogenisis
the way the cells get blood flow to them
What is non-disjunction
failure to separate homologist pairs or sister chromatids
Homologous chromosomes separate durring what phase of meiosis
Anaphase 1
where can non disjunction occur
In anaphase 1 and 2
homologist pairs form tetrads durring what phase of meiosis
Prophase 1
what is a tetrad
2 homologist shromosomes or 4 chromatids
in what phase do dyads separate
anaphase 2
where do tetrads separate
anaphase 1
what disease is a result of nondisjunction
Down syndrome
