Cancer
When a cell does not replicate at the correct rate
What creates a tumor?
What is a homologous chromosome?
The same genes at the same loci but they are not identical and can have different traits
Chromosomes align on the metaphase plate
What is metaphase?
XX is for female while XY is for
Male
The age at which females start producing eggs
Birth
Type of tumor that can not spread through the blood stream.
What is a benign tumor?
Name one thing that occurs in Prophase 1.
Nucleolus disappears, spindle fibers form in aster fashion, homologous chromosomes undergo synapsis to form tetrads, crossing over occurs
Spindle fibers attach to kinetochore, centromeres arrive at opposite poles, nuclear envelope breaks down
What is prometaphase?
Having an extra chromosome
What is a Trisomy?
The amount of polar bodies produced during oogenesis
3
What are 3 processes that can help Cancer patients?
Radiation, Chemotherapy, and Surgery.
What does telophase/cytokinesis result in?
Four daughter cells (haploid gametes)
Separation of chromosomes for diploid cells
What is the purpose for Mitosis?
A syndrome where the woman is sterile with undeveloped breasts, ovaries, and is short.
Turners Syndrome or XO
The chromosomes and the organelles are replicated in what phase of the cell cycle
G1
When a tumor travels through other parts of the body
What is metasize
When the homologues are held together by the chiasmata during crossing over, what has to line up?
The loci
Cytokinesis starts to occur
What is late anaphase
What are the characteristics for xyy?
Normal male, taller, below average intelligence
How many genes do prokaryotes have vs eukaryotes?
prokaryotic cells have 3000 and eukaryotic cells have 30000
What is a Pet Scan?
A machine that glows up where ever the tumor has spread.
When the chromosomes duplicate what does that result in?
Two homologous chromosomes and four sister chromatids.
Cytoplasmic clevage
What is cytokinesis?
The type of trisomy is klinefelter’s syndrome.
What is Trisomy 23
this is continued while meiosis allows for a way to keep chromosome number constant in species
