Mitosis
What is mitotic?
The phase in which Independent Assortment Occurs.
What is Metaphase 1?
the phase in which all of the chromosomes are copied.
What is the S phase?
Missing a chromosome (45 chromosomes).
What is monosomy?
Found in bone marrow, muscle, heart, kidney, fat, and specific neurons.
Where are somatic stem cells found?
Can start in anaphase but ends in telophase.
When does cytokinesis start and end?
Release spindle fibers in an aster formation, and begin migration to opposite ends of the cell.
What do centrioles do in prophase?
Has uncontrolled cell growth restricted to an area.
what is a benign tumor?
Usually occurs when the egg becomes older.
Why does nondisjunction occur?
Very common in the body, but restricted as to what cell they can become.
What is a multipotent stem cell?
When the cell grows to be two times the original length and the cell wall forms dividing the cell into two equal parts.
What is binary fission?
Results in the separation of homologous pair/chromosomes.
What is the result of Anaphase 1?
The part of Interphase where the DNA of a cell replicates.
What is S Phase?
Results in a normal male.
What is XYY?
An embryo that is 3-5 days old, and only has 150 stem cells.
Chromatin wraps around histones.
How does chromatin condense into chromosome?
Synapsis occurs and then the chromosomes exchange genetic information at the chiasmata.
How does genetic variation occur in Prophase 1?
Screening, Surgery, Radiation, Chemotherapy, and Nothing.
What are possible treatments for a tumor?
When there is an extra copy of the 21 chromosome.
How does Down Syndrome occur?
They are capable of reduplicating themselves and can replace and repair damaged/diseased tissue.
How can stem cells help treat diseases?
Daughter cells begin to form, the nuclear envelope and nucleolus reform, and a contractile ring of actin is formed.
What happens in telophase?
Results in 4 haploid cells (23 chromosomes)
What is the end result of meiosis?
DNA and proteins are a tangled mass when a eukaryotic cell is not dividing.
What is chromatin?
Eye, brain, and circulatory defects. Cleft Palate. Rarely lives more than a few months.
What are the symptoms of Patau Syndrome?
They are adult stem cells reprogrammed to embryonic stem cell-like state.
What are induced pluripotent stem cells?
